This pad is good for about, oh, a couple of weeks. Pretty soon the buttons stop working and your steps just don't register. It also slips A LOT and you'll end up on the other side of the room from where you started. And one more thing, don't even try Stardard on this... you'll make an E every time.If you want a really good pad, the metal ones are REALLY good. ... The 1 inch pads work really well...
