Dissatisfied, the film does not stick to the sides

I am very disappointed with this protective window. I did not expect that it covers the entire screen, with rounded edges is impossible, against the contour of the window, it does not stick at all. I think the dust will seep and that as and it will be worse and worse.
Note that I am not the film off again, only raises one was enough. I probably écaller up iphone 0.01mm but otherwise flush.
I bought the same glass for my wife for iphone5 and I have no complaints. by cons for iphone 6 to avoid! (FYI the sticker for removing the protective cap for iphone 5 was the wrong side :))
against by the quality of the finger slips and touched, I did nothing wrong, it's perfect.

I am disappointed :(
