I recieved one of these for christmas to use for my work boots. Every night I place my work boots on the dryer and let them dry overnight. I can say that it does work, it is just a fan. I had a extra DC adapter around and used that. However it only worked for 2 weeks. One morning I went to put on my boots and the power light was on, but the fan was not running. 2 weeks.
