content: junk you get what you pay for. you better make sure someone is with you even if youve been on one before. im 5ft. 7 and i have to set it at over 6ft. to be able to get back up.that probably wouldnt be so bad but now you are not lined up with the back so its very uncomfortable. its a wonder they havnt been sued yet. also the ankle braces are cheesy and uncomfortable. im sorry i tried to go cheap. i was better off going to sports authority for 200. i got a reebock that i can return much more easily if i dont like it. im going to try and give no stars as its not worth 1 star but i already put it in and i dont know if i can change it.
