As far as how good this product is I cannot say, for, after ordering one and waiting over two weeks for it to be shipped out I get a message in my e-mail indicating that my order has been canceled. This is following an e-mail I received a few days earlier saying:"We sincerely apologize for the delay of your order. All our orders are usually shipped within 24 hours, however there has been a delay from the manufacturer on the following product: Honeywell Carbon Tower HeaterWe will ship out your order as soon as we receive shipment. The shipping department will provide you with tracking information via email.Thank you for your patience and understanding and for providing us with the opportunity to be of service to you."So based on the failure of the order being completed I am going to have to give an unsatisfactory grade on this product.
