I have the Gerbings gloves and jacket liner and love them, I wonder why it took me over 20 years to get heated gear. Phoenixsteve covered many of the things I would say. The biggest con is getting dressed and plugged in, it has to be done in the correct order and is a bit of a pain. However, I have a Firstgear dual controller and really like it, you can really dial in the perfect temp rather than it getting too hot, unplugging only to be too cold. Plus I rarely have the controller on 10 so I'm not drawing full voltage from the bike. It's now such a joy to be riding in 40 degrees and feel completely comfortable, rather than it being a painful endurance.
