I love my chili pad. We have had it for over 2 years. We purchased the dual control. My heatflashes are GONE. This unit is the best for us “average aged” women. We live in Lake Havasu City where it can get to 110 in the summer. I turn my chili pad on an hour before bed and it is GREAT crawling into a nice COOL bed. The customer service is GREAT. After the summer I ship my unit back to the factory for a cleaning and a tune up. They have never charged me for this service. I pay for the freight and they clean it out for FREE. I have and would always recommend this product to all my friends. Thank you for a GREAT product.
