I also purchased the marware 'protection plus pack' for my brand new MacBook and not too happy with them. like everyone one, the keyboard cover seems too small. it *barely* covers the kb and it has hasn't happened to me (but has to a poster here) but the edges are sown and a little rough and i'm scared it will leave marks on the screen.
And like the other poster with the black handrest on his white macbook (i have the white in white) its never stuck down properly and the top edges are curling. i've contacted marware about the problem and they have shipped me a replacement. they were pretty quick responding to my email too so i'm very happy with their follow-up to my problem.
With the protection
plus pack i also got a microfibre sleeve. its made out of the same material as the kb cover, which is good, but the sleeve is too big for my MacBook. i didn't really need the sleeve since i already bought a incase neoprene case/sleeve at the same time i ordered the MacBook but it didn't cost that much more to get it. it's still usable, but i wish it was a bit tighter. i'll use it with a messenger style bag thats got a padded compartment for a laptop. the sleeve will stop it getting scratched up, which isn't too much of a problem b/c i have my MacBook covered with shieldzone's invisibleSHIELD 'Full Body Shield'
