Product review (5 stars): Nice, simple, ambient conditions monitor.
This is an awesome device. It's nice size, easy to read, and simple to set-up. The bad translation of the user manual is understandable, and yet comical. You'll laugh as you read that you must "burst through the battery compartment". But easy. Once setup you don't have to bother with again.
It's nice to see the humidity and know when to run things like the dryer and dishwasher, and when not to.
