AI-generated summary
The Brother TN-135BK is a pretty safe bet if you’ve got a compatible Brother mono laser and you want something that just works without messing around. At £42.06 ex-VAT, it’s priced like a “proper OEM” cartridge, so the value depends on how many pages you actually get between replacements. If your print volume is steady and you hate the hassle of mediocre third-party yields, this is the sort of toner that tends to deliver consistent black text and fewer reliability headaches.
I’d only steer you away if you’re chasing the absolute cheapest per-page cost and you print in high volume. For that, OEMs like this often lose out to compatible/compatible reman cartridges that can be materially cheaper—assuming your business is okay with the odd variance in yield and occasional printer-setting quirks. Overall: buy this if consistency and low risk matter more than squeezing every penny out of the cartridge; think twice if cost-per-page is your main KPI and you’re comfortable trialling alternatives.
