What do you guys think about this case OEM

It looks interesting, but be cautious about the snap between the front and the back sections, especially if you have the clip arrangement on the back. There have been some issues with these clips not being sturdy (on other similar cases) and the case will open if bumped. Another caution is having the X clipped to a belt with the face out - too easy to accidentally damage the screen. Safer to have a holster where the X screen is protected by facing "in."
 
Not familiar on this exact one, but in my experience with Body Glove, it makes the phone bulky as hell!! My BB's, iPhone, etc mage it about 2-3 times the size. I didnt like them at all. Nice feel though.
