[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]: Bought 4 of these in different colors worst buy I ever made they are very poorly made and rip after one day of packing it please save your self some time and money and dont order
[A]: negative


[Q]: All-In-All I like the product. Still learning what works best. Have tried with and without oil. First try without oil some of the popped corn was burned. I feel this is more a learning experience for me and not the fault of the popper. Nice size for storing. Very easy clean up. The user guide was a nice surprise. I recommend this product without reservation. It is easy to use, now that I have figured out timing and such. I would highly recommend
[A]:
positive
