For me, I find the install some what difficult. You have to align the pre-cut holes for the volume button, power, phone jack..etc exactly for each of the pieces. I had to readjust it couple of times and thought I got everything right but the last piece over lapped just so. Same holds true for the piece that covers the front. I tried to re-align it properly but afraid I might rip it (see previous post above with screen shot). The package also includes a glass protective film (nice touch). However, If you try to fit that in, and the previous step is not done EXACTLY, it will overlap and create bubbles/gaps. Fitting a rectangle protective film onto rectangle cut, at least for me can be challenging. Without this glass protective film, when you slide your fingers across the screen, your finger will catch against the edges. Speaking of edges, this does not protect the silver edges around the phone. Lastly, using the included ear bud, every so often the jack comes out just enough that you can't hear sound/music anymore.
Needless to say, I am returning mine for a refund.
