I just got my TPU case in the mail yesterday, black with smoked back. Here's my take on it:
I already had one of those black silicone hard rubber-ish feeling cases on my phone and I liked it, but it had kind of a honeycome back and I couldn't see the back of the phone like the words HTC and my little droid eating an apple sticker, so I bought a TPU smoked case.
I like how I can see through the smoke
I like how the rubber-ish silicone part of the TPU case is just like my old case
I don't like how the buttons on the case take more pressing than my old case did to activate the phone's button underneath. My old case had little indents underneath the case buttons so it made pressing the buttons easier.
The hybrid smoked backing does scratch easy. So far I have one day of use on it, and already I'm getting typical scuffs and scratches all over it
I'm thinking my old case offers a little more protection than this new TPU case
I like the price of the TPU case, set my back 6 bucks shipped
I like how it fits like a glove
I like the hard backing idea they have and being able to see through the smoke
Overall, I'd buy another TPU case if need be, but if they start offering my old case with a non-honeycome more see-through backing, although not a completely hard backing like the TPU case, I'd buy one of those first.
