In our office, the Brother HL-L8360CDW is the unsung hero. It churns out reports, invoices, and internal documents day in and day out without complaint. But this workhorse has a voracious appetite, and its diet consists of toner cartridges. For years, we stuck religiously to the manufacturer’s original equipment (OEM) cartridges, paying the premium price for the promise of perfect quality and flawless compatibility. The cost, however, began to feel like a recurring tax on productivity. Every “Toner Low” warning was a harbinger of another significant expense, chipping away at the budget. This is the dilemma faced by countless small businesses and heavy home users: how do you keep printing costs from spiralling out of control without sacrificing quality? The market is flooded with third-party compatible cartridges, all promising OEM performance at a fraction of the price. This led us to test the Cool Toner TN423 Compatible Toner Cartridge 4-Pack, a product that could either be the solution to our budget woes or a cautionary tale in the making.

What to Consider Before Buying Compatible Toner Cartridges
A set of toner cartridges is more than just coloured powder in a plastic shell; it’s a key component for keeping business operations, academic work, and home projects running smoothly. The primary benefit of exploring compatible cartridges is, without a doubt, the dramatic cost savings. For offices that print hundreds or thousands of pages a month, switching from OEM to a reliable compatible brand can translate into substantial annual savings, freeing up capital for other essential needs. They offer a lifeline to those who find the price of original cartridges prohibitive, ensuring that a high-quality laser printer doesn’t become an expensive paperweight.
The ideal customer for this type of product is someone facing high-volume printing needs where budget is a primary concern. This includes small businesses, schools, non-profits, and home offices that print multi-page documents, drafts, and internal reports where perfect colour fidelity is not the absolute top priority. However, a compatible cartridge set like the Cool Toner TN423 Compatible Toner Cartridge 4-Pack might not be suitable for professional graphic design studios or photography businesses that require flawless, calibrated colour accuracy for client-facing proofs. Likewise, users who are extremely risk-averse or whose printers are still under a strict warranty may prefer to stick with OEM cartridges to avoid any potential, albeit rare, compatibility issues. For them, investing in the manufacturer’s own supplies is a price paid for peace of mind.
Before investing, consider these crucial points in detail:
- Compatibility & Chip Recognition: This is the most critical factor. Modern cartridges come with a chip that communicates with the printer, verifying the cartridge and tracking toner levels. A faulty or poorly programmed chip can result in the printer refusing to recognise the cartridge. Always double-check that your exact printer model is listed as compatible, as we did for our Brother HL-L8360CDW.
- Page Yield & Cost-Per-Page: Look beyond the initial purchase price and evaluate the advertised page yield. The Cool Toner TN423 Compatible Toner Cartridge 4-Pack boasts a high yield of 6,500 pages for black and 4,000 for each colour, based on 5% coverage. Calculating the cost-per-page (Total Price / Page Yield) is the best way to understand the true long-term value and savings compared to OEM options.
- Print Quality & Consistency: This is where compatible cartridges can be hit-or-miss. While many produce excellent results for text and business graphics, some can struggle with colour accuracy or consistency. We recommend looking for reviews that specifically mention the quality of both black text and colour prints to gauge if it meets your standards.
- Build Quality & Ease of Installation: A well-made compatible cartridge should fit into your printer as seamlessly as an original. It should feel solid, with no toner leakage or flimsy parts. The installation process should be identical to swapping an OEM cartridge, requiring no special instructions or modifications to get it working.
Making an informed decision requires balancing the immense cost benefits against the potential risks, however small. For many, the savings are too significant to ignore.

Unboxing and First Impressions of the Cool Toner TN423 Cartridges
The Cool Toner TN423 Compatible Toner Cartridge 4-Pack arrived in a sturdy, professional-looking box. Upon opening it, we were immediately impressed by the packaging. Each of the four cartridges—Black, Cyan, Magenta, and Yellow—was individually sealed in a black, light-proof bag and cradled securely in thick, custom-fit foam. One user had noted the “emballage est toujours bien protégé par une mousse anti choc” (the packaging is always well protected by anti-shock foam), and our experience confirmed this. This level of protection is reassuring, as it minimises the risk of damage during shipping, which can lead to toner leaks and faulty cartridges.
Handling the cartridges themselves, they felt solid and well-constructed. We compared them side-by-side with the outgoing empty OEM cartridges, and the shape, size, and locking mechanisms were virtually identical. There were no signs of cheap plastic or poor assembly. Each cartridge came with the necessary protective covers over the drum and toner port, which were easily removed. The presence of a pre-installed smart chip on each unit was a key feature we were looking for, as this is essential for the “plug-and-play” experience we hoped for. Initial impressions were very positive; this didn’t feel like a cheap, corner-cutting product but rather a serious, value-oriented alternative. You can see the full product specifications and packaging details for yourself.

A Deep Dive into the Cool Toner TN423’s Performance
A good first impression is one thing, but the true test of any toner cartridge is its performance day in and day out. We installed the full set of the Cool Toner TN423 Compatible Toner Cartridge 4-Pack into our Brother HL-L8360CDW to evaluate its installation process, print quality, and long-term value proposition. Over several weeks, we subjected it to a variety of tasks, from printing dense, text-heavy legal documents to full-colour charts and marketing flyers.
Installation and Compatibility: A Seamless Swap?
The single biggest fear when moving to a third-party toner is compatibility. A cartridge that your printer refuses to recognise is nothing more than a plastic brick. We’re happy to report that the installation process for the Cool Toner cartridges was completely straightforward and painless. Following the printer’s on-screen instructions, we removed the old OEM cartridges and slotted the new ones in. They clicked into place with the same satisfying firmness as the originals. There was no struggle, no forcing, and no ambiguity. After closing the printer lid, it whirred for a moment to calibrate and then immediately recognised all four cartridges as full. The toner levels displayed correctly on the printer’s touchscreen, a clear sign that the pre-installed chips were working perfectly. This aligns with the experience of many satisfied users, with one stating they “si sostituiscono facilmente e non danno nessun errore” (are easily replaced and give no errors).
However, it’s important to acknowledge that this seamless experience isn’t universal. A scan of user feedback reveals a minority of cases where printers, like the DCP-L8410CDW, failed to recognise the cartridges. One frustrated user noted, “Toner werden nicht wie in der Produktbeschreibung erkannt” (Toner not recognised as described in the product description). Another mentioned confusion over installation, asking if they needed to “line up the lines,” suggesting a lack of included instructions could be a pain point for less experienced users. While our installation was flawless, these reports indicate that quality control, while generally good, may not be 100% perfect across all batches. This represents the small but real risk associated with compatible cartridges versus the near-guaranteed success of OEM.
Print Quality Analysis: Crisp Text and Vibrant Colours?
This is where the rubber meets the road. For the vast majority of our office printing, the primary requirement is sharp, legible black text. On this front, the Cool Toner TN423 Compatible Toner Cartridge 4-Pack performed exceptionally well. We printed dozens of multi-page reports, and the black text was consistently deep, crisp, and free of smudging or artifacts. When compared side-by-side with a page printed using an original Brother cartridge, it was nearly impossible to tell the difference. This confirms what many users have found; as one Italian reviewer put it, “il toner nero… non mostra differenze rispetto al toner originale” (the black toner shows no difference compared to the original). For any business that primarily prints text-based documents, this compatible black toner is an absolute win.
Colour printing is a more nuanced story. For internal business use—charts in a presentation, colour-coded spreadsheets, or simple logos on an invoice—the results were more than satisfactory. The colours were bright, saturated, and made our documents look professional. However, when we pushed the cartridges with more demanding tasks, like printing a full-page, high-resolution image on premium paper, some limitations appeared. We noticed a slight deviation from the original colours; the magenta was a little oversaturated and the yellow wasn’t quite as vibrant as the OEM version. This echoes the most common complaint from critical users, one of whom stated the cartridges “produce nothing like the colours they are supposed to.” Another user reported a more severe issue of “coulures d’encre” (toner runs) and toner failing to adhere to the paper, which suggests a potential defect that could cause serious problems. Our conclusion on print quality is clear: for everyday business and text printing, it’s excellent. For professional, colour-critical graphic design work, you may want to stick with the manufacturer’s original toner.
Page Yield and Long-Term Value: Does the Savings Hold Up?
The primary motivation for buying the Cool Toner TN423 Compatible Toner Cartridge 4-Pack is the promise of long-term value, and this is anchored in its high page yield. The black cartridge is rated for an impressive 6,500 pages, while each of the three colour cartridges is rated for 4,000 pages (at the industry standard 5% coverage). This standard represents a typical business letter, not a full-page photo. In our testing, after printing approximately 1,500 mixed-use pages, the printer’s toner level indicator had dropped by a predictable and reasonable amount, suggesting the advertised yields are realistic.
The financial implications are staggering. A full set of original Brother TN-423 cartridges can cost three to four times as much as this compatible 4-pack. When you factor in the high yield, the cost-per-page plummets, translating into hundreds of pounds in savings over the life of the cartridges. This is a game-changer for small businesses, as one user who runs two identical printers with these cartridges happily reported, calling them a “direct replacement for the OEM brother cartridges at a fraction of the cost.” The value proposition is undeniably the strongest feature of this product. The ability to print freely without constantly worrying about the cost of toner is liberating. If you’re looking to dramatically reduce your printing overhead, you should seriously check the current price on this high-yield 4-pack. The only caveat is the risk of receiving a defective cartridge, such as one user who reported the “yellow cartridge shows empty,” which would require a replacement to realize the full value.
What Other Users Are Saying
Our positive experience is reflected in the feedback from many other users. A small business owner praised the product, saying, “The product arrived quickly… The toner cartridges are clean and are a direct replacement for the OEM brother cartridges at a fraction of the cost.” Another user who prints 150+ page duplex catalogues was impressed with the performance, noting they were “compatibili al 100% buona resa” (100% compatible, good yield). The sentiment of excellent value for money is a recurring theme, with many stating they would buy them again due to the perfect print quality and high page count achieved.
However, the feedback is not universally positive, highlighting the inherent inconsistency that can come with third-party consumables. The most severe complaints centre around a total failure to work. One German user warned “NICHT KAUFEN! Toner werden nicht wie in der Produktbeschreibung erkannt” (DO NOT BUY! Toner is not recognised as described). Others point to significant print quality failures, such as streaking, poor colour reproduction, and toner not fusing to the paper correctly, with one French user describing it as a “catastrophe” that required cleaning the entire printer. These negative experiences, while seemingly in the minority, are a crucial part of the overall picture and underscore the trade-off between cost and guaranteed OEM quality.
How Does the Cool Toner TN423 Compare to Other Options?
To provide context, it’s helpful to see how the Cool Toner TN423 Compatible Toner Cartridge 4-Pack fits into the broader market. We’ve compared it against three distinct alternatives, each serving a different type of user and printer ecosystem.
1. HP W1350X High Yield LaserJet Toner Black
- Original HP Toner Cartridge – exceptional reliability and consistent print quality
- Page Yield: 2400 Per Cartridge
The HP W1350X is an Original Equipment Manufacturer (OEM) cartridge designed for specific HP LaserJet printers. This isn’t a direct competitor for a Brother user, but it represents the OEM alternative. Choosing this cartridge means paying a significant premium for guaranteed performance, flawless compatibility, and the manufacturer’s seal of approval. A user might prefer the HP W1350X if they own a compatible HP printer, are still within their warranty period, and prioritize absolute reliability and print consistency above all else. It’s the risk-free choice, but that peace of mind comes at a much higher cost-per-page compared to the Cool Toner solution.
2. Brother TN-3480 Black High Yield Toner Cartridge
- Prints 8,000 pages in accordance with ISO/IEC 19752
- Genuine Brother TN-3480 black high yield laser toner cartridge, delivering an increased print volume and lower cost per page
This is another OEM cartridge, but from Brother themselves, albeit for a different series of printers. It serves as the benchmark against which compatible cartridges are measured. Like the HP cartridge, the Brother TN-3480 promises perfect integration, optimal print quality, and zero risk of compatibility errors. Someone who owns a compatible Brother printer might choose this official cartridge if their print work is client-facing and requires the most professional finish possible, or if they’ve had a bad experience with third-party supplies in the past. It’s the gold standard for quality and reliability, but it represents the very high cost that drives users to seek out alternatives like the Cool Toner TN423 Compatible Toner Cartridge 4-Pack.
3. colorfly B230 Toner Cartridge High Capacity
- 🔹 Compatible Toner Cartridges: Colorfly B225 B235 B230 Toner can be used for replacing original toner cartridge 006R04400 and 006R04399 (Not Original)
- 🔹 Page Yield: 3,000 pages per B230 black toner cartridge (At 5% coverage of A4 paper).
The colorfly B230 cartridge is a direct parallel to the Cool Toner product but for a different brand ecosystem—in this case, Xerox printers. It offers the same value proposition: a high-yield, third-party compatible cartridge at a steep discount compared to the OEM version. A user who owns a Xerox B230, B225, or B235 printer would consider this for the exact same reasons we tested the Cool Toner: to dramatically cut printing costs for high-volume needs. This comparison shows that the market for value-driven compatible toner is robust across all major printer brands, offering similar benefits and potential risks regardless of the manufacturer.
Our Final Verdict: Is the Cool Toner TN423 4-Pack the Right Choice for Your Printer?
After extensive testing and analysis, our verdict on the Cool Toner TN423 Compatible Toner Cartridge 4-Pack is overwhelmingly positive, with a few important caveats. For its target audience—small businesses, home offices, and anyone with high-volume printing needs focused on text and internal documents—this 4-pack offers almost unbelievable value. The cost savings are immediate and substantial, the installation is straightforward, and the quality of black text is practically indistinguishable from the OEM original. The high page yield ensures that the value continues long after the initial purchase, liberating you from the constant anxiety of expensive toner replacement.
However, this is not a product for perfectionists who demand flawless, professionally calibrated colour for graphic design or photographic work. The potential for slight colour inaccuracies and the small but non-zero risk of receiving a faulty or unrecognised cartridge are the trade-offs for the enormous savings. If your priority is reducing operational costs for everyday printing, we believe this trade-off is well worth it. The Cool Toner TN423 Compatible Toner Cartridge 4-Pack successfully delivers on its promise of affordable, reliable printing. If you’re tired of paying exorbitant prices for OEM toner, we wholeheartedly recommend you give this cost-effective 4-pack a try and see the savings for yourself.
