In about 10 years, we have purchased 5 of several similar models. The first one, after using 4 years, we gave to a friend, who is still using it. The second one lasted a couple years. The third one quit in 3 months, but we had thrown the receipt away, never dreaming one would quit in such a short time, based on the other 2. The next one lasted a little over a year, then started making noises, and the fan quit. The one we have now is about a year old, and seems to be OK. So it's hard to say how long one will last. Love them, just wish they all lasted as long as the first one.
