I purchased this dual zone wine cooler in 2018 and it continues to work great. Last year I had a problem with the upper colder zone, for white wine and beer, as it wasn't reaching the set temperature, so the compressor was running longer and more often. I called the support department's toll free number and they quickly determined the problem was with the sensors. They shipped 2 new sensors, one for each zone, and emailed the instructions to replace them. Seeing I am somewhat handy, I was able to replace the sensors and put it back together. It worked fine and the zones were reaching the set temperature for only 5 months and then the same thing happened. I called the support department and they are shipping 2 more sensors. I must say the company stands behind their products with great support.
