I have one. No, I don't really like it. It's buggy. When the power goes off, it saves the settings, but the clock resets. I have never been able to get their software (computer) to work, and I gave up. Programs that, for instance, turn on fans when the temp gets to 79 degrees, work sometimes, sometimes not. Every once in a while I notice that a light is supposed to be on, but isn't. Then it works fine. Just kind of flaky. I wouldn't use it to control anything that is CRITICAL. Like water temp.
