I purchased the 950XL about a month ago. Our family has two children in college and they write a lot of papers, we use our printer and computer for letters, work and cards. This ink is very dependable and appears to last a long time with the use we give the printer.Ink dries fast and never has smeared. We have been using HP ink for at least a decade now. Never had any problems at all with any HP ink product.
This my second high yield cartridge. There have been questions about its performance. It out lasts two of the regular replacements so it minimizes the hassle of running out of ink and is more efficient. The convenience of buying and delivery is a good feature.
