I use the Amzer case - which I think is the same thing at the TPU you mention?? Anyway, you got a great deal on the price! I paid $9 each and got three different colors. Already had one (gray) that I like, but paid $15 for that one!!
I like these because they aren't sticky, cover all the vital parts and look pretty good. ALSO, they fit into the Verizon holster from that combo you mention. So, if you already have that, you are good to go...
