question:
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!
answer:
negative

question:
very disappointing product! In less than a year its doesn't work properly! After 40min of use it turns off, no matter if charged or no! Wouldn't buy again
answer:
negative

question:
I was excited to have the opportunity to preview this book and look forward to using my slow cooker more often. I really like that this book has recipes that I have not seen elsewhere and not just your standard pulled pork, chili and soup recipes. There is a section for breakfast something I had not thought about using my slow cooker for. The recipes are creative and healthy. The author includes variation tips with each recipe and the ingredients are easy to source. There is a section with vegetarian recipes and a section with simple sides at the end of the book.
answer:
positive
