[Samsung Galaxy S7 Edge Accessories] meyerweb:
Spigen Liquid Crystal: The first case I bought. Ordered it even before I had my phone. Definitely high quality. Probably the most precisely aligned, shaped and molded openings for all the ports, mics and speaker. It's all soft TPU, both the back and the bumper, and the pebble finish inside the back means there's no rainbow effect. Best of all the buttons are perfect. They add no resistance over using the phone without a case, they provide a very tactile feel, and a positive click when activiated. The best button feel of any of the clear cases by far. This case adds minimal bulk to the phone. This (along with the Poetic and Vena ) is the thinnest of any of these cases. The TPU is also reasonably grippy, and doesn't readily slip out of my fingers.

On the downside, these very thin cases are probably the least protective in this group. Did I mention the TPU is thin? And while it has a lip at the top and bottom to protect the screen when you place it face down, the lips aren't very big, so it raises the phone off the surface less than most of the others. I dropped my Edge face down on a flat surface in this case, and the screen shattered. I'm not blaming the case, though. It impacted along the right side of the screen, so the same thing might have happened in any of these cases.

Spigen's perfect cutouts:

The screen is raised a little bit off a surface, but not by a much as some of the other cases:

Spigen's buttons. They don't look special, but they just WORK. Everyone else should copy these buttons.

Ulak Clear Slim: Except for one thing, this would be my favorite case of the bunch. It has an acrylic back combined with a TPU bumper. The TPU is noticably thicker than the Spigen's bumpers. There's an air bubble at each corner, which may (or may not?) help cushion any impacts there. The lip at the top and bottom is quite a bit taller than the Spigen's, and it has raised "feet" on the back to protect the acrylic screen from being scratched when you set it down. The acrylic back is very clear, and really shows off the back of the phone better than the phones with TPU backs.

The edges are a bit more slippery than the Spigen, though not terribly so, and the acrylic back is a fingerprint magnet. But those aren't what disappoint me the most, though. The biggest problem is the buttons. They require much more pressure to push than the Spigen, and there's no tactile feedback at all. Very disappointing. And there's really no excuse for selling a case wtih second-rate buttons. Just buy a few of your competitors cases that do buttons right (like the Spigen, above), and reverse engineer them. If Uak just fixed the buttons, this would be my number 1 choice without question. Someone else who posts her tested this case, though, and said the buttons on his were fine, so I'm sending this one back and will try another sample. Hopefully the buttons on that one will be better.

Update (5/19): Other than the buttons, I liked this case well enough to give it another try. I returned the first one, and ordered a second. This one has better buttons. Not the best, but better. The volume buttons are almost on par with the Spigen's, and certainly good enough that I'll have no problem using them. The power button is still not on par with what I expect. But since I normally turn the phone on with the home button, that's not a major issue for me. This is now my preferred clear case for the Edge.

Oh, one minor annoyance. The product is supposed to come with a cardboard template that you can use to cut out your own picture to insert in the back of the case. A nice touch to personalize your phone. Mine was missing the template, and Ulak's customer service was totally useless. They insisted it was Amazon's problem (as if Amazon manufactured and packed the case), and refused to do anything at all to remedy the missing feature. If the case didn't have such potential, the lousy customer service would make this a "no sale."

Update (5/19): As mentioned above, I bought a second copy of this case. The second one didn't come with the cardboard template either.

The "bubble" in the corners of the Ulak case. Does this really help with impact resistance? Your guess is as good as mine.

One of the "feet" on the back of the Ulack, which should help prevent scratches on the back.

The lips at the top and bottom keep the screen well off a surface if you put it face down. The might help, a little, if you drop it face down.

This final pic should give you an idea of just how clear the back of this case is. Very nice.
