If you're skeptical about using this product let me tell you why you shouldn't be: 1)Great Quality 2)Surprisingly Easy to Use... AND Dataproducts, the manufacturer, gives a 100% guarantee that it is compatible with HP printer it's made for. You can't go wrong. I've used it several times and I'm very happy with it...

This was the first time I had to replace my cartridge and it was so easy a child could have done it. The instructions were clear and easy to follow and the product performs just as well as the original cartridge, to say nothing for the savings. I would highly recommend it to anyone. In addition, let me say the service from Amazon was outstanding...

it's a very good product. like other refill kits i've tried, the ink smears more and dries more slowly than the original cartridge. however, the instructions are simple and the kit is more complete and easier to use than the office depot version. since staples stopped selling it, i'm stocking up.

and yes, rubber gloves won't hurt, and definitely refill outside or on newspaper.
