After six weeks now my first summary to cover:
+ Class processes, protects the iPhone perfectly
+ Reception is generally better (Congstar)
Wobbles + Perfect fit for the iPhone, nothing
- Better battery life nil because I realize nothing
- The promised 40% better reception is an advertising statement. Yes, a bar more in the section is in there, but I do not even have to take off the antennas. This brings my opinion nothing.
Conclusion:
Not the cheapest cover on the market and certainly no revolution in Empfangsberbesserung.
However, anyone who is looking for a top shell and processed like to the gag with the antenna wants to show his friends and colleagues on the iPhone, can access safely.
