Overall the unit is pretty solidly made. If like me, you intend to use this as a keezer, be aware that you can't simply shut the high temp warning alarm off. That means every time the unit kicks on, the alarm will beep incessantly until your temp controller shuts back off. You cn kill the alarm by pressing a button on the controller unit, but you'd have to do that each time the power cycles. It took some time and some tinkering, but I was able to reduce the alarm sound significantly - but not completely. While reasonable for typical use, it seems like the user should have the option to override this feature.
