Bought a powersupport MBP 15" and also a Moshi trackguard from Xavin - trusted dealer

am *extremely* happy with my powersupport - although a bit hard to put in the quality is as expected from powersupport, simply impeccable - never seen a better screen protection than this!

Moshi trackguard is also good - sensitive enough to be used but has a slight texture on the surface that's slightly different from the totally smooth clickpad on the MBP - but I'm still happy with it. Just takes awhile getting used to.

Overall both are very good products - thanks to xavin for bringing it in
