Well worth the money!
Easy install, warm and has 3 settings. These are great as I can choose which grips I want yet always have access to warm hands in inclimate weather. I can disconnect and keep them in my dry packs. Easy pray and well worth the money.
My grips are 4.125” or just over 10cm and fit perfectly.

So far they're great!
Just installed but so far so good. The installation was simple but time consuming for me as I had to remove a lot of body panels. They don't seem to have any effect on my grip or when I use the throttle. So far, the lowest setting is more than enough. I use these in conjunction with motorcycle muffs and honestly so far I think it's the perfect combination. My hands are warm and I don't have any added bulk to them. Will update if anything goes wrong or stands out with more use but for now I'd say they're completely worth the money if you're regularly riding in the cold.

Awesome! Game changer if u ride in cold weather
These are amazing! I’m not real big on leaving reviews. Takes something either really good or really bad. Well these heated grips are on the really good side. They’re a game changer. I’ve been using them for about a month now here in Buffalo, where it’s been prettttty cold. I can ride in temps lower than I’ve ever ridden in before, without wearing thick bulky gloves. The first couple settings actually get too hot sometimes. I was super skeptical about these because I’ve bought similar heated pads before, that hardly even heated up and died after like 5 minutes. But these things get piping hot and stay there. I don’t give anything 5 stars, cuz there’s always room for improvement, but if I could give these 4.9 out of 5, I would. If I had to say something negative about these, it would be that they’re thick on top of my current grips, but that’s the nature of the beast with this type of product, and I have smaller hands. If you’ve been scrolling through different versions of this type of product, just buy these and u will be more than happy.

Used for skid steer. Adjusting heat is perfect.
Perfect for my open cab skid steer. Only downside is the button sticky pad is poor quality but easy fix pick what glue you want and stays in place.

Great to have on a cheap bike!
The right grip provides ample heat, but the left grip is lacking for certain. The left provides what feel like half the heat output. The right gets hot enough to make lift my hand to let it cool, so that's good. Its cheap, you get bunk ones occasionally.
