I love this solar fridge/ freezer.  It kept its temperature perfectly.  My only issue is modern technology and how to set it. This was very frustrating for myself and I had someone else who was old school finally get it right but gave him alot of trouble in understanding it. So hopefully you will have better luck then me. The good news is if it gets unplugged it does keep your previous settings which was so helpful for me when I had no one around. This cooler ran great on solar, house and you can even purchase a battery for it. this is a great unit and I'm thinking of buying even the bigger one.
