My mamba was dragging ass and ended up being a faulty piece of junk so I got the G700 which is awesome, and it was really smooth on my pad for about a month (the g700 is only about a month old now) and now it's somewhat slow again. There's still meat on the feet so is there anything I can do to speed it up - besides buying new feet? My pad is fine and not worn it's a steelseries 9HD and both surfaces are clean
