Product review (5 stars): I like these and I'd buy more
I bought 2 of these and an AcuRite 02081M Weather Station.
Amazingly, the wireless sensor on all three were able to figure out which base unit they were paired to when I first plugged in the batteries. I was worried about this. But, it was "magic" and it "just worked".
They have been working great from that point on.
The display is clear & sharp and easy to read in normal room-lighting. It is a little harder to read in lower light (the base units are in the garage) because there is no back-light on the base units.
For the price, they are great.
The remote sensor works well out to 100' ("real life").
