Although I have used several attempts on my judgment until the glass eventually sat properly, I am very satisfied. The "board" is actually sucks so well on the display found that not a single bubble has emerged. The enclosed cloth I find in order, and the adhesive film strips (also there) in my opinion is more effective. But why I can not say anything, is the resilience or the protection factor, since my phone as yet had no crashes. Due to the relatively low price (if you ... compares with MediaMarkt) I speak from a strong buy recommendation.
