Disadvantage (From End user experience)
1. Locking mechanism could scratch Back screen protector easily, careful when you take back slide off.
2. Liner pad on the right side of case was fall apart after install and remove several times.
3. Signal Distortion (from my case only)
I test using iPhone 4 white AT&T without any wraps along with *3001#12345#* command. I tried at least three times before make this conclusion.
Without case - Signal around -99 to -94 dB
Without case but "Death Grip" Situation - Signal around -116 to -113 dab
With Xtrucase - Signal around -118 to -114 dB
With Element Vapor Pro (With Good adjustment) - Signal around -105 to -96 dB
I think that my problem is pad on right side of case fall off which cause distance too thin to isolate between metal and also no pad around "Dead Grip" Position since I tried "Dead Grip" position, Result almost identical to with Xtrucase on.
I really like the look of Xtrucase, but I have to switch back to Vapor Pro white edition and try to solve Pad Problem before switch back to Xtrucase. I might contact support and ask for extra pad since it start to fall off since second time I put the case on. (If Xtrucase support can contact me via PM, it would be nice.)
Or anybody have any idea where to get pad sticker from retail store?
