I have had this freezer/frig for almost 8 months now. Have used it on several week long camping trips and it has not failed me yet. I have had it run on my 12v 100 amp Li iron po4 battery for 4 days(at zero degrees F) and the battery was down to about 29 % charge left. When not using it for camping we use to as an extra freezer and it has been running almost everyday of the last 8 months with no problems.You can hear it running but it is not very loud at all, no problem with sleeping and it in your camper. It cools down pretty fast, but think it would be better to have most items frozen first if you are using it as a freezer. I seldom use it as a frig. but functions fine in that mode. It has a smaller compartment that is frig. only and it stays about 15 degrees or so above the freezer. Items will freeze in that compartment if you leave the item for several days and the freezer at 0 degrees.When I first received the freezer/frig. I had trouble turning it on and adjusting the temperature. I was just pushing down on the "button area" and nothing happened no matter how hard I pushed or where I pushed. I was very upset and sent the company a "heated" email. They answered in a few hours with questions and suggestions, even offering to swap out the control panel-(plug and play I guess) or having me send the unit back to amazon. To make a long story short, they continued to contact me and with ideas for me to try. Finally by accident I pushed my thumb flat on the button and held it there and what do you know it turned off and on and I was able to adjust the temperature. Problem solved-use your thumb, you don't have to push hard and just leave it there till the display starts blinking-read the small owners booklet.Yes, I would buy another if I needed one and recommend this unit to you!Update 7-13-24: Just got back from an extended 2 week camping trip. The frig continues to impress me and worked great the whole time with minimum power consumption from my lithium 12v batteries. We still use it for an extra freezer at home on occasion and trips to Costco. Works wonderful and thinking about buying another one.Update 2-1-25: Had relatives come visit for 5 weeks and used the frig/freezer in our camper. Worked great and they thought it was "neat frig/freezer". I have had it for about 4 years now and I am very satisfied with my purchase.
