Review on 🔋 Feet Cosy Battery-Powered Foot Warmers by Gavin Dunne

I modified mine and they are really HOT! Yes they work but I changed mine. After reading the reviews I heard a lot of problems with batteries not lasting as long. I use them for hunting and in winter I sit in the snow all day, my feet are very cold and the heating pads don't fit. I bought these insoles along with a PWM dimmer and made my own 10ah. LIFEPO4 battery. I've been running for 12 hours with heated gloves and these battery powered insoles with no problem. If I'm not careful, I could burn my legs with the new attitude. In addition, the solder joint on the outsole can break if you are not careful. I had to modify the solder joint with new wire and add a loop to the connection to avoid stressing the solder joint. I lost my first pair and will buy another pair and do the same mods again. If you're not afraid to modify them, they work very well and pump out a lot of heat.
