I really like the case design overall. Most of the Nexus 7 cases out there are overly bulky. This one wraps nicely around the edge of the case, and fits snugly. It is still a little thicker than I would have like, but I can deal with it.
As many reviewers have stated, there are some issues with the auto sleep/wake magnet. Thanks to the great customer service of Poetic, before my cover arrived, I was notified that I would be receiving an updated version. There were some good things and bad about the new case. I had to modify the magnet positioning myself to get it to work right, and cut out the stylus loop. There seems to be a good warranty on this item, so if it doesn't work right you might be able to request an additional replacement, but I didn't bother, since mine is working great now.
The first cover arrived, and I did notice that the magnet was too powerful as was stated in the email I got from them. I did like the overall design, and everything was very accessible, except half of the speaker was covered. I found that if I pulled the cover far enough when I had it open, it would not put the 7 to sleep, but who wants to force their cover open when they are trying to read or whatever.
When the second one arrived, I did notice some design updates. Some good, and some bad. The first I noticed was the stylus loop. They made it larger, so it should be more durable, and hold a stylus more firmly than the original, but they moved it so it obscures the volume rocker now. The speaker port is now perforations that expose the whole speaker rather than a slot that covered half of it. I didn't notice any sound quality differences, but the smaller holes seem like they would protect it better. Also, on the inside of the flap there is a small black strap that I can only think is used to hold the flap to the case when you have it open. On the original, this was a very thin strap that rode right on the edge of the screen, but didn't block it. On the new one, it is a thicker, sturdier strap, but it blocks about 2mm of the edge of the screen. Maybe that is not what it was intended for, but now I am really confused about its purpose.
The magnet itself was an issue. I could not get it to trigger the magnetic switch on the 7 no matter where I placed it. Finally I decided to just go ahead and pop a few stitches to see what the deal was. I noticed that they fixed the issue of the magnet being too strong by casing it on one side in nickel or something to attenuate one of the polarities. The problem was that the attenuated side was inside of the flap. I flipped the magnet over, and it was working much better. I toyed around a bit to find the best placement, then put a dab of glue to keep it in place. Now that function works perfectly.
I tried to see if I could do something similar with the old case, but the magnet is glued in there pretty good, and I couldn't get it out very easily without risking damage to the materials.
Hopefully they fix some of these design/quality issues for future purchases, since the case itself is pretty darn nice. In the meantime in true Android fashion, if you want it to work better, you can hack it. :D
