Bests & Worsts Reviews from Amazon

We have two of these, one at each of our houses. We bought the second because we were initially extremely impressed with the industrial design and and accuracy of the temp control. However after a little over a year (just out of warranty) the temp sensor on the unit that we use the most broke, no longer turning off when it reaches the correct temp. Because it was out of warranty, I took it apart and was a little appalled to see how cheap the electrical design is for a device that costs so much. Rather than using a thermo-couple, there is a kinda janky setup with a pair of metal disks that deform as they heat pushing a linear potentiometer with springs as the rebound. In a harsh environment like a kitchen, this scheme just seems designed to fail as condensation collects in the springs etc. in addition to what I considered to be a poor design, my unit also had the thermal paste applied without care, half of the paste was to the side of rather than under the metal thermal disk. I was able to fix the unit by taking it apart, cleaning the springs and applying fresh thermal paste. However, I expect that this won't be the last time that I need to service it. Unfortunately, further disassembly is almost impossible because rather than assembling it wth screws, the temp sensor is assembled with 14 very small very thin bent sheet metal tabs that at best will open and close one additional time before snapping.
