I've used compatible drums in other printers with no problems. This one has been nothing but a headache since I put it in. First, it didn't want to reset the counter, then when it did, it only printed about 50 pages before the page counter shut everything down again. I haven't been able to get the thing reset, which means I'm having to replace it WAY early. An expensive problem, even with the nice price for the pair. Thankfully, this problem is happening on my home printer, not my office printer. If it were at work, I'd definitely be screaming even louder abut it (and probably using language I shouldn't in an office environment.) When it did work, the printing I got was very clan, crisp, and of good quality. The instructions to install it are pretty standard, so no complaints there. I'll wait to see about the reliability until I see if the other drum that came with this set gives me the same problems. It's almost like this was a previously used drum, not a new one, except the packaging was still sealed and all the little tabs and plastic protective bits were still in place.
