After I received the foot warmer / toe warmers on time, and I'm used to it from Amazon, I wanted to also try out immediately whether this toe warmers all this promise, what the manufacturer says. It's really true. The heat is on me about eight hours after gluing the pads still there. You just have to do it right and stick the pads according to package instructions on the socks or shoes. There are wonderful Pads and I no longer want missen.Ich have suffered much from cold feet and not anymore, thanks to the great pads. All who claim that these pads do not last a full eight hours, the heat would not have anything gemacht..Ich correct these pads order at any time what I will do. For me, no other pads come on the stockings or in the shoe. Thanks again to the manufacturer. A strong buy recommendation.,
