Brother Printer TN331BK Toner Cartridge

I cannot tell you HOW MANY FAULTY TONERS we have gone through. We always buy geniune brother through Amazon Prime, and they LEAK! Then we cant return them b/c its been past the date. We use a lot of toner so we always keep a new one on hand. I ordered this one 3 months ago, but just started using it and its still 80% full but creating a large grey streak down the middle of every page (covers 50% of page). Ive tried everything but it still leaks. This is very frustrating when trying to run a business.

have bought quite few times, already good, no issues.

Great cartridge.

Performs as expected.

No complaint about how the cartridge works, copies are very good. My problem is how many pages a cartridge is supposed to print. The last two TN331BK cartridges I purchased, didnt come close to the page count they are supposed to. Page count advertised on the box says 2500 pages. The first cartridge was short about 800 pages, this last one over 1,000. I realize heavier printing or two sided printing would cause more toner to be used, but I think my page totals should be coming closer to what Brother advertises the toner to do.

Very good product. Excellent service.

Just as advertised.

exactly as expected... no issues with quality

So impressed that the system is set up to order automatically when refill is needed!
