Product review (5 stars): 2nd order .. I love these everspring sensors
I had tried the Axxx 4 way sensor and had problems. I have one of these light and another temp-humidity sensors. Love them both, battery level detection, easy addtion to the network (vera 3).

Awesome awesome awesome

good design
good rugged construction
security screws,
sticky tape to  ease initial mounting.

My only 'complain' would be the monitor / price.
I would happly pay 20$ for one without the screen. I mounted mine high and it is not 'as useful', so this is only a price / utility / extra feature.

ps, I got 2 more, one for the basement and one for a cheese cave. (I the cheese cave, the screen is an awesome addition.

No performance or construction or networking complaints ... so farm 5 months, its perfect!
