Poor personal experience

Product delivered without instructions and without the helpful advice on the direction of installation.
I find myself back 4 times before asking it.
And the product is a bewildering fragility, he broke into a thousand pieces (that is indeed the glass!) In the last attempt.

My advice: if you take it, go on the internet before to see clearly how to proceed.
Personally, my problem occurred when we had to put it on the display glass and it is supposed to auto-join. Me, he never self-adhere ... even pressing a little harder on it.
