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!

I bought these shoes for my daughter and my daughter loved it as they look good in rainbow colors but these shoes broke in less than 5 months. I never expected this from SKETCHERS. Really disappointed. Not worth buying.

I was really excited to try this but with my mare. When I opened the package it was very easy to tell the bit had been used and a sharpie was used to color in spots where the sweet iron had Ben rubbed away and where teethe had left scuff marks. It also looks like someone used clear nail polish to make the copper look shiny. The bit is also not the same as the one in the picture
