Found them to be good. They do pop off when the kids get too excited with the games their playing, but that's because the original pads are basically worn off. They are easy to go back on again though.

If you are thinking of getting these for your Xbox One i would NOT reccomend them. They sit too loose on the thumb sticks and move when u apply pressure. They can be knocked off very easily too. If you really want these on your controller you would have to consider glueing them in place.

Fits the PS4 controller very well not loose at all.
