I love these nails! I have very small toenails, and these fit perfectly on them, making my toenails look actually normal for once. I was also really impressed by how long they lased (2+ weeks, depending on how tough you are on your feet). I'm pretty hard on my feet, so sometimes if I knocked into things they became a little unsettled. But that was nothing a tiny bit of nail glue couldn't fix! Depending on your toenail size (if you have smaller nails, like I do), you can actually get 2 uses out of the set by adjusting the larger sizes to fit your nails because they're really easy to cut (since it comes with 3 large toenail sizes and a variety of other sizes).
I basically spent the entire summer wearing various shades/colors, and I was in the country, where you don't really wear shoes a lot during the summer. I even went swimming in them, and I had no issues with them staying on.
Basically, I have nothing but positive things to say! Definitely recommend as a solution to expensive pedicures (which I love but my wallet does not).
