iHandstick snap-on dresses your iPhone

Ever tried having a long gaming session on your iPhone or iPod Touch, do you get hand cramp?, I do, so when I saw this baby my first thought was that is so simple why didn’t someone release it ages ago before I messed up my hands with hours of game play.
Anyway want to give this a go? $16.99 plus shipping and it’s all yours.
