Okayice Magnetic Hand Warmers Rechargeable 2 Pack, Ultra Slim Electric Handwarmers,3 Levels Smart Heating,Portable, UL Certified, Pocket-Sized Camping Golf Hunting Essentials, Gifts for Men

I have yet to use these on a below freezing day, but they appear to hold a charge and heat quickly. They are very warm on the middle setting and get very hot at the top setting. Convenient size and shape easily fits into your hands.

These heat up very quickly. My husband has used them daily since purchased and has recommended them to others. Easy to charge and it's super convenient that they cling to each other so they don't get lost. Also lightweight and very comfortable to keep in coat or vest pockets without feeling like your pockets are weighing you down. Perfect for handling cold winter temps if you need to be outside!

These hand warmers work very well. With the temperatures being so cold I have used them quite a bit this winter. They charge up very easily and last several hours. You can put in your pocket or inside your gloves. You can set on low, medium and high. They heat up quickly. They come with wrist bands so you can put them around your wrist. The price was excellent for the work they do. I purchased 3 sets for my family and plan to buy more for other family.

I bought both this and the OCOOPA UT4. I think this lasts longer and warms up faster, but it's not as hot and the thickness and width of this is ever so slightly too big for it to be held comfortably in the hands. Might be okay for someone with extra large hands, but the ergonomics of the more thinner/rectangular OCOOPA one feels much better in the hand. Aside from that, it's nice and does the job. Might be a good one to keep in pockets, whereas the OCOOPA one I think feels better to hold around. If you care about sticking them together via the rear magnet, the OCOOPA one has stronger magnets, but overall fairly negligible. Silicone straps on both are about the same. I do like that the OCOOPA one has rubber covers for the USB-C ports built in, where as this one does not. Might have to be a bit more careful on a rainy/snowy/wet day. I'll probably be returning it, but if you can get a good deal on this, it's definitely not a bad buy.

These little guys are a big improvement over the older, larger hand warmers, which were the size of soap bars. These smaller ones fit into your gloves really well. They’re almost too hot, but your hands are definitely much warmer than heated gloves with built-in heating elements, which are barely lukewarm. The charge and heat lasts at least a couple hours if not longer. Great value. I bought two pair.

Ordered these as a gift and the person loves them. They stay warm for a long time and work great. She liked the bands and shared they are very useful. These were used during bad weather power outage and helped to stay warm.

Wish the battery life was longer. Other than that they are great rechargeable hand warmers.

These work ok and were a good value. Charged and ready to use right out of the box. I mainly got these with the intention to wear them in my gloves to keep my fingers warm, either while using my snowblower or when driving my convertible. Yesterday I tried putting them in my back pockets to warm my but-tocks on a 30-minute drive. I had them on High and they stung my cheeks. I turned them down to Medium but not much better. I also tried them in my gloves; they fit but take away a lot of dexterity and grip. While my palms were warm, my fingers were still cold. Later I tried putting them under my thighs; that was better. But now I wish they were bigger. 🤣 I guess there’s just no pleasing me. 🤦🏽‍♂️ Still 5 stars because they do work well by themselves. 👍🏽
