I keep meaning to buy one. Looks like I'll order this tonight.

 

I tried glass. It did NOT work well with our touch screens. If you have the same results, be VERY careful removing it so you don't destroy the actual screen.

 

I had to reposition it twice, so was careful to lift it from the edge very gently. it seems to not stick as well as the ones do on the iPhone for example, so I'm hoping it comes off easily in a year if it lasts that long.

 

I received mine this weekend, but it was hot as balls here so I didn't put it in yet.
