This is another great Innovera product. It's priced at a fraction of the OEM equipment and - so far - works as well.
Since these drums are rated for 25,000 pages and I don't make very many copies / print very much, I can't really talk about longevity / durability of this product. The original drum lasted almost 6 years.
Based on my excellent prior experience with Innovera laser and inkjet cartridges I see no reason to expect less from this product. If it does fail early, Innovera's customer service is ... almost ... as good as OnTime Supplies :-)
