Warmers work very well and have temperature setting to keep your hands warm even on the coldest days. They are rechargeable so no batteries to replace. The charge lasts long so i only had to charge once every gew days. Perfect for extended outdoor adventures in the cold. Highly recommended.

Good fit for me

Due to my age, I have poor circulation in my fingers, so keeping my hands warm is important. These hand warmers, measuring about 4 inches high and ¾ inch thick, fit comfortably in my hands. The dual-sided heat design works great — the larger heat surface keeps my fingers warm, while the smaller side warms my palms. The lowest heat setting is sufficient to keep my fingers comfortable, and I only use the highest setting when wearing gloves. I haven't needed to use the two middle settings yet. The battery life is excellent for warmers of this size, and the rechargeable feature was a must for me. Mine came with two charging cables. While I haven't timed the battery life, the specs indicate up to 14 hours on the low setting. Based on my experience, I've carried them in my coat pockets on the warm setting all day without running out of heat.

Great little gadget

Perfect hand size, gets really warm. The only thing is that it takes a while to charge, but if you remember to plug it in before going to bed its fine.
