A bit bulky but that's to be expected when they include thermal wiring and batteries in a pouched wrist. Otherwise. they work great for me. I have Raynaud's disease, a wonderful leftover from when I had frostbite working in ice cold temps at Fisherman's Terminal in the 70's.My fingers turn purple (and hurt), then white and numb. I also now experience other problems as a result so these reasonably priced heated gloves saved me from Raynaud's aftermath. You can spend a lot more money to get the same protection like $250 at REI. Did quit a bit of research before purchasing my Volt gloves. The instructions say even when they are not in use. you need to charge the batteries so I will follow that advice. They kept my hands a very comfortable warm (like I was inside my house instead of outside), during the winter of 2015/2016. I only had to use the 1st setting as 2nd was too warm. If 2nd was too warm, I can imagine what setting 3 is like. A really cold winter will be the final test. Am happy with my purchase!

Worth every nickel. What a top notch product...WOW!!!

I bought a pair from Amazon and sent them back because one of the batteries wouldn't charge and neither of the batteries worked in the gloves. I really wanted a pair of these gloves, so I tried ordering them directly from the manufacturer (voltheat.com). The gloves from the manufacturer work perfectly. The batteries charge properly and work in the gloves just the way I expected them to. Interestingly, the gloves from voltheat came with yellow batteries, as shown on their website. The gloves from Amazon had black batteries. Knock-off's?

Have only had to use these twice since I rec'd them but both times they worked great! Would recommend.

Bought these for skiing and they worked very well. Batteries last longer after each recharge. Didn't quite make it through the whole day on low power but they were still warm even after running out. Very good product.
