As I have previously tested some other Bumper and these have fallen by at least one to two weeks apart, I then decided to use these little "more expensive" Bumper.
He is, like many other Car of two parts. A hard plastic part (black), which is located on the outer surfaces of the iPhone and a soft rubber lip (light gray), which surrounds the iPhone. These parts are bonded to each other / processed and do not dissolve even after 2 months. The buttons are not used individually, but are incorporated directly in the shell and can not be lost or fall off.
This was with the other bumpers that I had not, and is a clear advantage of this product.
Positives:
+ Stuck, does not slip
+ Buttons and rubber lip incorporated directly into Bumper
+ No sharp corners -> all topped off
+ Feels wertig
+ Already survived several falls and protect the edges of my iPhones always perfect
+ Does not increase the iPhone heavily
Negative
- Is stuck in one spot to, so my screen protector is lifted there and there is a small air pocket
- Bumper could down to where the connections are to be a bit harder / more stable
Conclusion
After two bad buys I've found the right product for me.
It is very well made, and protects the phone from drops and the drop, optimally from scratches and damage.
I am still very excited about the durability of this Bumpers.
