Product review (3 stars): Slow, but solid.
Works well enough, but I don't know if I'd buy it again if I could do over. Website is slowwwww to update temperature, and is incredibly non-intuitive to get set up. Can't comment on Android as I have only use iOS app, which hasn't seen an update for a long time... Programmers must have perfected the thing two years ago, right? Not really. It crashed about a dozen times before staying lit on iPhone 6. Worked better on 4 and 4s (which were current about the time it was updated) and iPad Air2. Once it's set up, it seems solid and runs fine for the most part. Definite step up over shining a flashlight to the deck door to see the thermometer mounted outside
