I've had this case for an iPhone 4S for almost two years and there are things I like and dislike about it.

LIKE:

1. Great cushioning, has survived a few drops onto concrete (whoops!).  Has a secondary plastic inner case with ribs.
2. Like the way it feels in my hand, solid grip.
3. Like the grab it has on smooth  and/or angled surfaces, like if I want to stick it on the car's console to act as navigator, it wont
  slip and slide around.

DISLIKE:

1. The black silicone picks up oil from skin, along with debris from inside your pockets.  Can get to looking greasy and cruddy after
  awhile.  Removing the inner plastic case for cleaning purposes is difficult and mine cracked a little bit as a result.
2. Hard to get out of pocket sometimes because of the bulk and the grippy silicone, and the supporting plastic "skeleton" inside does
  not hold it to the phone very well so sometimes the outer covering will peel away from the phone and you have to pop it back into
  place.
3. No moisture protection, but I knew this going in so this is not a star deduction.  Just felt like mentioning it because if I had to
  buy another case it would probably be an Otterbox or something with water resistance.  As it is, I will probably continue to carry
  this case for the remainder of the time I have the phone

I have read that people had a problem with the belt clip, and I agree it seems like a weak point.  It just seems flimsy.  I do not wear a belt-clipped phone so I haven't tested it.  I did keep the clip because it converts into a little stand for watching movies on the phone.  It works great for that purpose.
