got mine off ebay, but the same thing.
wish they did a 4 x 4 ft size at least, but I think it's great for a quick skirmish setup - hills made by t-shirts, and the mat's flexible enought to work with that nicely.
didn't have too much trouble with shedding - and sprayed with matt varnish as per someone's advice, which seems to have worked.
plasti-dip would be even better I imagine
just scattered some other colours of flock to variegate the green a bit, and the tracks done the same.
