Qpad Glidz 2.8 or whatever

Just bought a packet of these things since I couldn't find a retailer of hyperglides in the U.K. for deathadder. So far the pack it comes in is very shiny has no instructions, no alcohol swab, the glides are very thin, the backing paper is very very hard to remove and the glides feel very flimsy. When applied the feel is ok but that should improve as they wear down i'm sure but basically try to avoid these 'qpad glidz' (precut hard teflon replacement mouse feet) and stick to hyperglides.
