My wife spends a lot of time using her sewing machine which is in the basement. She had always complained about her feet being cold. Neither Dyson nor Lasko nor any other heater seemed to help. Finally comes Newair AH-400! Fits nicely under her desk and provides enough local warmth. Money well spent! Their customer service is excellent as well especially call-back feature. They do get back and try to make you happy the best they can. Highly recommended.
