Agreed$200 ?!? No way.
You can get a pair of heated gloves for WAY less. Plus, the battery lead easier to install (exactly the same as for a Battery Tender), and you can use them on multiple bikes. And they keep every part of your hand warm, not just the part that contacts the grips.
Can't say enough about the Hippo Hands, I use heated gloves and vest on the Rocket, I recently set up a plug in for them on my BMW r65, but since I added the Hippo Hands to it, I leave the heated gloves home, no need for them, ridden down to 14 F so far, hands stayed toasty warm, believe it or not. The seller, Dan, is also a member of my local BMW club. http://www.hippohands.com/I recently purchased hippo hands, I do not intend though to be riding in extreme cold weather.
