The print quality is just as good as the OEM cartridge in the beginning but starts to fade quicker than OEM. Resulting in shorter lifespan and less prints per cartridge.
I was hesitant to buy the re-manufactured toner at first but for the price difference I thought I’d try it. That was several years ago and since then I buy the re-manufactured toner if it’s available (the 128 is only available online - but I can still get it next day). I’ve only ever had one bad cartridge in the roughly 40 that I’ve purchased. But I was able to return it for a full refund at a local Staples store. These are definitely worth the $20-30 difference in price for the same output quantity.
