I had one of the first cases they made. Too big and ugly. They look better now, but still too big for me.

If you are clumsy or want the best drop protection, then go for it. I remember watching videos of a phone being thrown around a room like a Frisbee.

Their protection is based upon the 3DO stuff that actually disperses energy. Look for the videos of the guys putting the stuff on their hand and then hitting it with a hammer. Cool.

I prefer looks over protection. :)
 
I picked up one of the Tech 21 leather flip cases off ebay and sold it on.

The leather quality was ok - not the best I've seen and not the worst. The top part of the back of the case has a fold seam in it, which you fold down when you want to take photos. It all seemed a bit of a fuss to me so decided to sell it on.
