Review on Upstartech Wireless Electric Multiple Shoveling by Jeff Callier

What a disappointment! I spend a lot of time outdoors and my feet are always cold so I was very happy to get them. They say they can be recharged at least 300 times so I was skeptical and was hoping for at least 9-12 months of service. I charge them twice a week. A month later, the right insole stopped working. It seems to charge but it still doesn't heat up. Immediately thereafter, the right insole suddenly became very hot on its own and then died. I was disappointed but still hopeful so I sent them back and exchanged them for a brand new pair from the same manufacturer. The second pair stopped working after a week on the third charge. The charge indicator kept changing color from red to green. I've tried adjusting the charger's position, different outlets, to no avail. The next day the right insert didn't work again. This is a week of service. I will spend some more money and try another manufacturer but what a poor quality product!
