This is the second time I've bought Valuetoner printer cartridges. The cartridges arrived very quickly and worked great once installed. I can't say anything about the durability of the cartridges, since the current one was only installed in November 2019. But judging by the amount of documents my husband prints every day, we should have switched cartridges by now. I am very satisfied with this product.
