I won an Orange Androidified TPU case from their Facebook contest a while back.
They don't add much bulk at all. Fits snugly and has just a slight lip around the screen which gives a slight bit of protection.
The texture is glossy and smooth, but has just enough grip to where I am not concerned about dropping it. I noticed a few minor line weight issues with the robot print, where a couple robots' outlines are thick in some spots from missing orange print. Very slight and not noticeable unless looking throughly.
The cutouts for the power, speaker, USB, bottom mic, and the secondary mic are clean. The power button cutout has to be reached around from the back or straight down to press, can't do it easily from the side and difficult from the front; must curl finger over the case material.
The volume controls had some hard, textured plastic over them different from the rest that really just made pressing them near impossible, very annoying. Must use the tip of my finger and dig in. Considering slitting the area down the middle to see if that flexes it enough for presses to register, or cutting out area entirely with a box cutter. Still will probably be less functional than stock like the power button; thick, functional overlays on each area would've helped these flush stock buttons.
I like the design and quality for an entry level case. Slips on and off quickly for basic protection in a pocket or whatnot. But the button issues prevent it from staying on.
