Stainless steel or anodized aluminum panels all around with powder coated frame, this is about as good of components as a refrigerator could be built with. I read a previous review about temperature fluctuations being from 40 degrees down to 32 degrees, if it was not known that this is normal, it might sound troubling. Refrigerators are designed to cool down to your desired temperature, then the cooling compressor turns off, it and is not supposed to turn back on until the inside temperatures have risen around 10 degrees, this is to avoid a system that has a compressor constantly turning on and off. Even thought the inside air temperatures may fluctuate by around 10 degrees, the actual temperature of the food items inside are not fluctuating quite that much. This is how all refrigerators function. I have a home refrigerator with a inside/outside thermometer setup, I have the outside temperature sensor on the inside of the refrigerator, and the compressor on my refrigerator regularly does not turn on until the inside temperature sensor is showing 42 degrees, and then it stays running until it cools the inside down to 32 degrees.
I bought this cooler 14 years ago. Still running strong regardless of the horrible environment it's been exposed to. It's been running outdoors in south west Florida near the Everglades so the humidity is relentless. Just starting to have some rust issues and some coil freezing. But I have never had it serviced. No matter how hot the day, it will have the coldest drinks.
We bought this for our bar/restaurant and it has served us well. It is very roomy for many selections of bottles/cans as well as plenty of storage for extra fruit and bar essentials. The only issue we had was with the hinges on the top of the unit as the edges are quite sharp and bartenders were cutting their hands as they skimmed them. I used a pair of snips to take the edge off the corners and then took a metal file to grind down a bit. That is the only design flaw, but otherwise an outstanding unit from TRUE.
