Stay away from Chatterbox, it's crap.
Myself and several friends wasted plenty of money on the top model GMRS-X2 and several have broke within the first year with only limited use. I just had a second unit fail, both after the warrenty was up.
JUNK
Those numbers doen't seem to bad considering thats Rear Wheel HP. Still it would be nice to see Yamaha set the bar high. I'm awaiting some hard numbers and an official press release from Yamaha. :popcom00:
