i got this mat for christmas and it was really fun and extremly cool... until it broke, four days after christmas. i was sooooo disappointed. i've wanted one for a year and when i got it, it was so much fun. anyone who tried had to wear socks, no shoes or barefoot, but i guess it didn't matter, because the back arrow did not respond anyways. the next day my sister, who also got a mat, claimed her back arrow didn't respond either. so now we don't have any mat even to share. i would not recomend this to my worst enemy. please save your money if you don't want to be as disapointed as i am.
