I purchased in June and hired an HVAC professional to install. After several calls to Nest support, it was determined that we had a faulty plate so we attempted to install the 2nd and again after several calls and a couple of hours, determined that that one wouldn't hold its charge long enough to install. In both cases, the window to return them had lapsed so I am out of $400 plus and then had to buy a regular thermostat to boot! Lesson here, do not buy this product until you are ready to install it!
negative

I absolutely love these! I've never installed something like this before. It took me a little longer than it prob would have taken most men, because I didn't think the directions were quite clear so I had to do some thinking on it but I'm proud of myself.
positive

This works great for snoring and sleep apnea. Just cut a 1" wide section and tape the center of your mouth at night and breathe through your nose all night! Much healthier! And much cheaper than those bulky, cumbersome cpap monstrosities!
