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!

Ex Output:
negative

Ex Input:
It's the worst purchase i have ever made. It tastes so much better at home in India. I feel they've made it really bland to sell here in America. It's also pretty old to be sold. Please don't put out your expectations too high if you're from India and have tasted this at home. Also overly expensive and I really regret wasting my money. I wish I had done something better

Ex Output:
negative

The first thing I noticed about this toothbrush holder is how well it's made. The materials used and the welding makes this toothbrush holder far superior than others I've held before. The stainless still goes well with all theme you may have in your restroom. Highly recommend it!

Ex Output:
positive
