The case looks fine, it’s solid, made of well finished metal, with special neoprene lining inside, to prevent phone from scratching, or moving inside the case. It fits the phone almost perfectly and it has holes for all ports, or side buttons plus a plastic glass covering phone screen. The phone’s function keys and QWERTY keyboard are not covered of course. The only functional issue which I have noticed is the access to top function keys as the case’s edge makes it little uncomfortable to reach those keys with you thumb.
You can use the case as it comes or make it wearable on your belt. You can use a special belt clip and mount it with a screw, which you can attach to the case. The mount mechanism works fine, the clip is holding belt well, it’s possible to rotate the phone around the mount, and to remove only if you press special button.
Unfortunately, the case is made of aluminum and as several-day-long test proved that the phone is loosing two or three bars of its signal indicator because the metal covering is screening network’s radio waves. It happens for both 2G and 3G modes. As a result it was difficult or even impossible to make or receive phone calls in places with poor network coverage. It also has huge impact on GPS functionality, as satellite signal is much weaker than mobile network waves. The conclusion is that the case will for sure make your phone safer but it can also make calling less comfortable. Moreover, the case screening feature probably increases phone’s power consumption and shortens battery life.
