I ride to work every morning [unless I see ice or it is already raining]. In the winter its around 30 at 7 am and I couldn't take the pain of the red frozen fingers anymore. I love these grips - so easy to put on - and they work so well. More time to ride! Its 60 to 70 degrees by 2 pm when I leave work, so I just don't turn them on. Just remember to switch them off when you park, and if you forgot, let your bike sit a bit after you realize what you did - or you will be popping that clutch! You probably will only forget once. No one I have shown them to has ever seen anything like them. No messing with the electronics on your handlebars or paying the high costs for those other grips. I consider the price equal to free for what they do for you. These are literally HOT! (Posted on 5/14/10)
These work very well. Only downside is wore out. The surface of the grip wore out so the coil was uncovered, and does not have grip able to separate from wiring at grip, thus, not easily set aside when not needed. Overall, serves its purpose well. Toasty hands, even through gloves. (Posted on 12/1/09)
Work great. Nice and warm. A great alternative to heated grips. Are easily removed and installed. If I think I need them or have just finished using them I wrap them around the crossbar on my KLRs. However, I've replaced two pairs over several years because they quit working. In one instance, one grip quit heating. In the other, both grips quit; checked power connection and switchbut still didn't work. ...but, buying another pair because they are so handy and warm. (Posted on 11/3/09)
They work as marketed - Easy to install and get very hot, very quickly.
They can be removed just as quickly when the weather takes a warm turn, but they are not bothersome just to keep on (given you don't mind a thicker grip). (Posted on 9/14/09)
