I bought two pairs, and I wish I had bought more. They are solidly constructed and seem very durable, as I already dropped one by accident and it bounced off the hard floor but still works. I am giving a pair as a gift. The low setting, one light, is very light heat. The medium, two lights, is perfect for me. The high heat, three lights, feels like it could burn your hand if handled on bare skin. Anyway, you won't be disappointed. They charge fast and stay charged for a long time, many hours.
