Have been using this ink in my aging (but still very serviceable) HP 1010 printer for years. Tried the cheaper alternatives only once--with not so good results. Will keep using HP 61. It serves me well.
I've been using HP ink for a long time I'm glad that it still is the best for my printer.Easy to replace, only takes a minute to install . I like to keep a box on hand in case i missed the "Ink low" sign.
