I have a Powerlet wired dual controller on by CBR 600. The gear and controller work great, but to avoid a bunch of wires running to the handlebar area I mounted it on the left side of the frame below the left front lower edge of the seat. The only problem is that in order to SAFELY adjust the heat on my liner or gloves I need to pull over and stop.
I have Powerlet wireless dual controllers installed on my GL 1800 on the front brake perch bracket. The controllers are right in my view and I can easily adjust the temperature on my and my rider's liners/gloves without taking my eyes too far off the road, not having to pull over and stop.
My only complaint is that Powerlet (and others?) should manufacture the gear with wires cleanly routed to exit the garmet in ONE strategically placed location and should strategically place a pocket large enough to contain the wireless controller as standard equipment on the liner/vest.
I was hoping Powerlet would have made these modifications on their new edition jacket/liner, but they didn't. My wife's liner is the old version, mine is the new version. I can't say I notice any difference in the efficiency of the heat output between the old and new vests.
Wireless is the only way to go!
