Product review (5 stars): A Real Bargain
This works perfectly, right out of the box. We got it to monitor temps in a detached greenhouse. The outdoor sender unit is in the greenhouse, and the indoor receiver unit is about 50 feet away, in our kitchen. There are three walls -- one exterior and two interior -- between the units. The temperature readings have been accurate since set-up. The large display is easily read. We feel like we got an excellent unit for a VERY reasonable price. Hopefully, it will last, but if not, it will be inexpensive and easy to replace.
