The overall build quality is good and the clarity of it’s material is great. Adhesive in the inner side of the glass is quite good and the silicone on the side of the case provide better grip of your phone. This product covers 2/3 of the phone surface. This concerns me that it will prevent the heat from the phone to be released into the air causing the phone to overheat. And there is the additional glass protector for the backside which also another heat trap for the phone.
Visibility of the phone screen reduce significantly when it is seen from the side, the manual says it is 25 degree if it is over 25 degree the screen will no longer visible. That is true because if you look at it from the side you can only see black screen as if it the screen were off.
If this product is just a tempered glass with minimum visibility from certain angle I believed that would be better.
