I bought one and it worked fine for 2 weeks. So I bought 2 more that were needed. The first died 3 weeks after first use. The second batch worked for 4 days and never got hot again. They returned the money for the second two. I wouldn't waste your time with that. Looking at all the other heaters on the market there doesn't seem to be any reliable heaters that Revain offer, I just keep looking
