This is my third unit of this size I have purchased on the last 5 years. The first one lasted two years and the second 14 months, both after the warranty ended and estimates on repairs was more than I paid for them. Both were a competitor brand. Hopefully this one lasts longer. But I do have to say this one works better so far than the other tow units did. Better features and it hold the temperature better.
