Yeah i have one, I'm 15 and have had mine for.. hmm 4 years.. and honestly I hate it.. I hardley use it because I hate feeling naseus in the morning.. Its also made me slightly paranoid, I hate people touching it or coming near it.. When I first got it I was 60 pounds and now im 75.. ish.. Since I have it there are things I cant do now.. lol Slip in Slide is outta of the question.. It's just annoying I mean I wear baggy clothes so know one can tell unless they concentrate really hard.. even then they couldnt tell what it is.. but its just annoying i guess..
