Just got mine and am very disappointed. Speck has managed to completely ruin their cases over the last two years. First last year with the switch from rubber grips to just part of the molded plastic, and now by inverting the grips on the back. Not only that, the case is more flimsy and flexes much easier.
I get they needed to make it flat for MagSafe, but the non MagSafe version is the same way.
These were my go to case for as long I can remember but I guess it's time to look for something new. My only hope is that their lower tier "candyshell" lineup that shows up on Amazon and in department stores is still good...
