Ok here are some pics of my Ebay TPU case taken with my OG Evo. Here is the link:
HTC EVO 4G LTE (SPRINT) TPU CASE GEL COVER | eBay
Seller shipped super quick, got the item in 3 days (would be quicker for most of the continental states). Comes in a package with this branding:
The case is a fairly solid TPU that is black glossy on the outside and matte/dull on the inside (ostensibly to protect/adhere to the phone itself without slipping). Goes on like any other TPU case, find the most pliable corner and put all the other ones in first. The case fits very snugly and securely, better than the smoke TPU case I had for my OG Evo.
First thing to notice is that it doesn't have any covering over the buttons, whereas some TPU cases have thinner membrane type areas over the buttons. Personally I think I prefer having the buttons covered, but this case is manufactured very well and cut pretty much perfectly for all ports and buttons.
There is a raised lip around the camera and flash that keeps the bezel around the camera lens from touching the surface the phone is laid on. The headphone port fits my modern-style headphone plug; older style plugs might have a little bit of trouble as it doesn't really have much room to spare. The kickstand cutout is generous enough to not hinder operation. The phone still stands firmly with the kickstand in all 3 directions possible.
The microphone and speaker holes are cut out accurately. Camera and power buttons are easily accessible and operable. Charging port cutout is fine, fit all the micro USB cables I have including one rectangular type; the early-days really blocky, chunky types might be a little tricky to fit, but there is a little give in the case that could help.
Volume rocker cutout also accurate and generous. The only flaw to speak of in the design is here, as the piece of rail above the rocker is thin and bends fairly easily. The other holes are small enough that the rail is well-supported. This is the area that makes me think I may want to try out another case that has covered buttons, since they seem to support the edge rail better. They also make the buttons easier to press if executed well.
The performance of this case is outstanding. Slips easily in and out of the picket and feels solid, yet the improvement in grip is at least 100%. I was always afraid I was going to drop the phone when it was naked. The raised lip around the screen helps a lot with swyping to the far side of the screen; because of its larger size than the OG Evo, I found my reaching swypes to often be messed up by the palm touching the close corner of the face. I expect most TPU cases to offer these improvements. In addition, fitment is really, really good, very snug.
All in all, for a $5 case this exceeded my expectations. The material and manufacturing quality are excellent, the only niggle I have is the open-hole design vs. membrane button covers.
For reference here is the OG Evo that is the basis for my comparisons:
The quality of this OG Evo TPU case was always below that of the Evo LTE case, with a more uneven and more raised seam, and the buttons with a little flashing on them. Still, in use, this case had some advantages.
