Review on 5200MAh Electric Rechargeable Double-Side Hand Warmer | Portable Pocket Hand Warmers & Phone Charger For Outdoor Sports | Heat Therapy Great For Women & Men In Winter By BRIGENIUS by Jaya Walsh

These items are one of the best purchases I’ve made on Revain. I have two; one for each hand. I use them every cold night and day. They have four heat levels and they go all day! They help improve circulation and help relieve my neuropathic pain. Their neatly designed hourglass shape fits perfectly in my hands. And you can also. use them to charge your iPhone! The only problem I’ve had has been that the black coating has worn off; likely from overuse! Good thing is that it has not diminished their ability to warm up my cold hands. Thanks to Bregenius for a very ‘smart’ product.
