I installed this drum in my office copier less than 2 months ago. And so far we have only printed/copied 2603 pages and they are already sold out! UPDATE: I received a new photoconductor in July and it has worked flawlessly so far. I hope the first one was just defective and this one lasts most of the 25,000 pages. If not, I'll update this review again. UPDATE: AGAIN. For about a month we've been getting a drum error message every time we type. Very frustrating. So the block only lasted 6 months, which for us was only 10,000 pages or 1/3 of the original. But it also costs 1/5 less. So we ended up saving only $50. So I'm keeping my 3 star rating.
