Don’t buy these !

These sucks suck compared to Lenz heated sucks , I’ve used Lenz heated socks for the last 2 years and hot tonics before that and Lenz by far is the best heated sock. The only reason I thought I try these is because I lost my Lenz batteries and socks . I had multiple issues w it going off when I changed settings blue tooth and at the highest setting it was nothing like a Lenz heated sock. I will be buying another Lenz sock setup and returning these
