Waaayy cheaper. Cant comment on difference in grip between the plastidip and the vinyl, as i havent tried the former. But its way better on my H20 than without it. Just stick it on the back and trim the edges with a razor blade.
For a dollar, definitely worth a try. If you like it keep it, if not then go for plastidip.
