Previously tip! Update: Second glass with errors!

A long-term rating is not there by myself but after a short time, I can say:
The assembly is actually simpler than in "normal" elastic films.
I have the glass installed in the bathroom as I had previously run for a few minutes the shower very hot.
When you create the first glass was wrong and I was afraid the worst. But I could raise no problem with the fingernail on a corner the glass again and just touched down. And above all without lint and dust under the glass.
Super! When using the iPad you notice no difference. Also I do not mind the switch now deeper.
Only fingerprints are clearly visible. Whether as a coat is it? ....

Update: We have now a mini iPad and this should be protected by glass. The first iPad's still all super.
So at the same time also ordered the iPad a glass.
When the procedure stick "foil" in the same bathroom with shower and so .... Has also so far works well - but what is it? On 2 sides, the glass is not right and it's on the air underneath.
At first I thought of dust or booze or something. But taking a closer look at a light source I can find any damage to the glass edge. Like a wave and a pimple. But totally tiny.
On the other point that is almost impossible to see. But by this damage, the glass is not on schedule and it is air on the edge underneath.

I've complained about it. The new is now back to normal.
