I now have 3 cases in addition to the stock bumper. I don't like the bumper, tho I kinda like the concept. I want a minimalist case, enough to protect from scratches and very minor drops. I've never broken a phone dropping it, and the stoutest case I've ever had was the Diztronic TPU case I used on my GS3.
The first case I got was
this Cimo. I really like the fit and feel of the Cimo. It offers good grip, the cutouts are all where they should be, and there aren't any sharp spots. I wish it were clear tho, as the frosted color obscures the bamboo back on my MXPE. I knew this when I bought it, so can't blame them. It's pretty thin, but it seems like they should be able to go a little thinner.
The second case I got was
this Vena Retain. I liked the clear back and the overall look, and the cutouts were all as perfect as they could be, but it had too many problems for me. You can see my
full review here, but my main complaints were:
1) There is a seam between the PC back and TPU sides of the case that is a little sharp.
2) The case is quite slippery. Aside from the power & volume buttons, the only texture on the sides is the little VENA logo on the button side. The other side is smooth top to bottom. And unlike other TPU cases I've had, this is glossy-smooth and slick. The back is polycarbonate, and it's even slicker than the TPU sides.
I'm actually curious if it would be possible to separate the TPU & PC parts of the case and make the TPU part into a bumper case, with the back naked.
The third case, which I just got a couple days ago and am currently using, is
this Tektide, which a couple people recommended earlier in the thread. It's totally clear, so it shows off the back unlike the Cimo, and it has no branding at all. Also, it's all TPU, so there are no seams like on the Vena, and while it doesn't have grippy texture on the sides, it still seems to offer better grip than the Vena. I need to pull out a micrometer to measure it, but I'm certain it's thinner than either of the others which is a win for me. If you're looking for drop protection, this is not for you, but if you're looking for the thinnest case you can get that offers a bit of protection against scratches from general use and minimal drops, this may be the way to go. The only real issue is the buttons (power/vol) are slightly harder to press than with other cases. This may bother you, but it can also be a benefit if you use a car mount with side-arms that tend to hit the volume buttons. It's also the cheapest of the 3.
TLDR; if you want the thinnest, clear case that gives pretty good grip and shows the look of your MXPE,
this Tektide may be the best option out there.
