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: The detachable belt clip - clever on its own because my bf could put the phone in the case screen side in, ostensibly protecting it and securing it to his belt without having unclip the thing. - was too big even with the internal shell. This was not evident until he clipped the whole contraption on the FIRST time and started on his motorcycle to work... It flew out of the clip while he took a turn, the screen protector and the phone screen itself broke, as did the kickstand on the shell. So needless to say, I'm unhappy. Especially since it meant replacing the phone, the screen was far too damaged to salvage, so I spent about $150 after purchasing and using ONE TIME this well-rated "protective" shell, hybrid screen protector, and belt clip that did not secure the phone. Lesson learned?

negative
