Just received one of these in the mail yesterday. So far I am very pleased. It fits perfectly and is clear in between the keys to allow for backlighting if you use it. The only downside is that the keys are printed on with pre-Lion layout. This doesn't bother me though since I know F3 "expose" is actually mission control and F4 "dashboard" is actually launchpad. All other keys are as they should be.

BTW I ordered it on OCT 28th and received it NOV 5th.
