Bests & Worsts Reviews from Amazon

Poor quality and poor customer service. This product as described is exactly what I want for my bathroom exhaust fan. Unfortunately, it doesn't work. I installed the device in a standard wall switch box, in a smallish bathroom, about 5' from the shower door. When the shower door is opened (after a shower) the humidity in the room is quite high, more than 70% as measured by other devices, such as a dehumidifier, high enough to condense on the bathroom walls. Nevertheless, the switch did not turn on. The only way I was able to get it to turn on was to exhale directly into the humidity sensor port and even then it didn't stay on more than a minute. The device has a setting adjustment for what humidity level triggers "on". The setting can be from 20-80. It didn't work on either extreme or anywhere between, nor did it work in the "default" position. Because the device would turn on when I exhaled into it, I thought it might be calibrated incorrectly and requested a replacement (rather than a refund) when I returned it. The replacement behaved in exactly the same way. The device instructions contain a number for Levition product support. I called, was on hold for 10-15 minutes, finally speaking to a person who led me through each step of the install instructions including settings. Although I had already done all these steps numerous times, I did them again while on the phone. The device still didn't work. This person took my phone number and email address and said someone would be in contact within 24 hours and abruptly hung up. Six days later I had not heard via either email or phone and called Leviton support again, and was again on hold for 15-20 minutes. When a person came on the line, I described my question, said I had called earlier, and asked if he could access that record. He replied that Leviton does not keep any record of customer contacts, so no, he could not. I described the situation again and he said the only thing he could offer was that I send the device to their quality control department so they could examine it. Since (after the first call to Leviton support, when I was told I'd be contacted) I had already returned the defective device to amazon, that was not an option. I asked to speak to a supervisor. The call was terminated on the Leviton end with no further resolution. The device appears to be robust and well constructed, but neither of the two I had worked. Leviton support can do nothing beyond reading the instruction page that comes with the device.
