Review title: On/Off control knob is wearing out bad after 7 months
Product review: On/Off control is wearing out. Called Service Center, they want to send whole new unit for $20.00 and you have to send back the cord from old unit. So it may cost you a total of $25.00 for a part that should be available at no charge. I should give this unit a 5 but customer service to me is 95% of the product.
