Bought a Speck See Thru for my new MBP 2010. Apparently they'd just nicked out the extra plastic near the magsafe connector...🙁
And yesterday when I tried to remove the case for the weekly clean up, I broke one of the hook holding the lower case...Long story short, I went out and got an Incase Hardshell(Black) today. I put it on just now, it fits great. Unlike Speck, they didn't cut out the extra plastic, the lower part seems to be newly built. But material-wise, I think speck has thicker plastic😱 Incase has slimmer plastic.(Incase's feels slightly slimmer in my hand) But the hooks on the Incase's seems to be built better, they feel tougher 🙄
My suggestion, buy both and return the one that you don't like 😛
