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!

Great helmet! Nice fit and great adjustments to get right fit. It’s very comfortable on and doesn’t slide around. Has good amount of padding. Great buy for the price.

I loved the rustic look of the tree skirt. It matches my rustic tree decor. I did press it prior to putting it around my tree, which made a huge difference in the look. I used a cloth to press it as was advised. I have a 9 foot tree, and it looks great around it.
