electric hand trimmers....opinions, reviews?

http://growace.com/product_info/speedee-trim-hand-held-machine-trimmer.html

anyone use this?

Sure would make trimming a lot easier but I shure as hell would not spend almost $200 for one.

yea, wish i could try one out first.

but for medium yeilders who cant justify a machine, and its a lot to do by hand, and you have carpel tunnel syndrome from work....its not a bad investment if it cuts time in half.

there is vid on youtube. cola in 1.2min, but he doesnt show the finished product....never timed myself on a cola that size by hand.
