This is the worst product I've ever used. The first one I ordered didn't work. Wayfair, to their credit, send me another one. It didn't work either! I must say the Wayfair representatives were kind and helpful. We decided to give it one more chance, so they sent a third unit. It worked for several months, but now it runs loud, and it won't hold a steady temperature. I will never, ever buy another Kalamera product again. Nothing against Wayfair, but this product was terrible. Don't buy a Kalamera!
