I've been using one all winter. Absolutely fantastic! Tried lots of other makes over the years, including BMW. Klan is the best by far. They're also fused to 5A which makes them compatible with the canbus socket on current bikes. I believe some other makes use more power which requires a separate socket to be wired direct from the battery. I love it. But that's just my opinion. Others speak equally highly of other makes. Buy one!
