From Mike R.
"I don't have first had experience, but a friend of mine from Minnesota has one and really enjoys it. He rides a bent and comes down for BRAG most every year; several times I've ridden alongside him and could hear the radio just fine. It's not "hi-fidelity" but definitely acceptable. I've been tempted to buy one myself several times. It seems to take a fair amount of abuse. YMMV
The first year he only had the radio, he quickly determined you needed the CD player for long trips since the radio can get spotty and boring after a while."
