Q: 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!

A: negative

Q: Terrible performing product. I have only had it 3 months and the brown coating is coming off and separation starting to show. It will just be a matter of time before water intrusion. This is the most expensive tarp I have ever bought and the worst performing. I would not recommend buying, and I will go back to mfg. for customer satisfaction.

A:
negative
