IT snaps on easy. Have removed it a couple of times no scratches. The sides come up to screen level so I'm buying a screen protector too as if you placed it upside down on a table there's no edge. Has a nice feel to it so it doesn't slide in my hand. it's very slim and only really adds the phones button height to the surround.
These are good until you get to about age 6. I change the sheets every other day. I had hoped to avoid going down the hormone treatment until my son was 7, am seriously reconsidering. use these in conjunction with a disposable bed mat or washable absorbant pad. It isn't a one stop solution in my opinion.
