Query: Not the best

I have owned this pad (not exact one, in blue) for 5 months and all of my friends own this pad as well. This pad works well for beginners, but once you have reached light, standard, and difficult it begins to slide around because it doesn't have a grip. I once had a party and when we were playing it, by the end of the song the pad had slid up about 2 feet and turned diagnally. I have also slipped and fallen using this pad. If you fold the pad there is a good possiblity that the sensors will move and the pad will become useless, this happened to my friend, so don't fold it if you buy it. I suggest that you don't buy this pad because you can probably get a much better one for only a few dollars more. In the end, spending a few more extra dollars will be worth it and you'll be safer.
