Query: HORRIBLE!!!!!!!!

plz do not buy this pad!!!.....i went out and brought this pad from toys-R-us since they were having a 50% off everything out of business sell...this pad is very cheap you unzip it and put the foam pad sensors inside and zip it back up and within 2 weeks my back arrow stopped working which i was very mad about and then i spent about 10 more dollars and brought a flat "konami" mat and that has been the best choice i made even though it slides alittle bit whenever i do a song on heavy it will not let you down!!!
