Product review (2 stars): There is probably a more reliable product out there.
Got this for a Christmas gift. Was pretty excited to keep tabs on garage, crawlspace, and attic. The garage sensor worked good for about 2 weeks, haven't yet got around to installing the other sensors, but have no luck in getting the garage unit going again, after spending a fair amount of time. My two bullet points about this product below:

- Nice app, easy to follow.
- Sensors appear cheap, and seem to be working about as good as they look.
