I gave up on this product after 2 tries, and I am now looking for another option. On the first model I received, the on/off switch was loose and no longer connected to anything inside the fridge. The manufacturer was great to deal with, and shipped me out a brand new unit at no charge. However, this one was defective as well. I plugged it in, switched it to the cold setting for 4 days, and it didn't get below room temperature. Although others may have had a great experience with this product, I have concluded that this is very poorly manufactured. I am in the process of getting a refund.
