I finished installing my palmguard and I'm not impressed. I love the look of it but it doesn't play well with my satin speck see thru. I managed to squeeze the palmguard on one side under the tab of the see thru. On the other side it keeps lifting and the tab keeps going under the palmguard.
I did purchase the palm guard and then sold it online. I didn't like the feeling of the material at all. The color is actually very close to the aluminum that uses on the macbook but you can still tell the different between them.
So far i've been using my macbook without the palm guard and i'm very happy about it. Just yesterday, my dog was playing around and she scratched my touch pad and the aluminum palm rest very hard. Guess what, there's nothing happen to my macbook at all.
I thin the palm guard is kind of over killing but if you think you hand will get dirty a lot when using your macbok, it is a good idea to purchase this thing.
