I find these very easy to use. Once you apply them, and cut your nails down to match, they have a really polished, salon look. I get a lot of compliments on the designs. They tend to last about two weeks which is great because I bang my nails around a lot. With any of the stick on nails, it comes down to if the shape matches the shape or arch of your nail - in terms of how long they last. The shape of these match me for sure!
