Ya' those things are great. And when hanger rats chewed up the knobs on two of them (sounds kinky, I know!

), I was mailed replacements before I had even paid for them (was asked to send a check after getting them) - was floored by that, even though the cost was small. The hanger rats disappeared almost immediately after a hanger cat moved in, so no more knob abuse.
These are great, too; made in America (hard to believe, given it is an electronic device, but true) by a small, niche company - expensive, but worth every penny. They are intended to use in home-built, walk in coolers, but being a polar bear that has lived in a climate hell hole for most of my life, I use them to control two window a/c units in my two most used rooms (this is in conjunction with my central a/c). In addition to being an ingenious and simple to install and operate device, the small company's customer service is really something else (including help with choosing appropriately sized, and high quality window a/c units for your specific application).
