Product review (4 stars): Good Value for the Money
After reading some of the reviews before purchasing, I was a little hesitant in purchasing. I have never been totally happy with any similar gadget, but have to say this product for the value works just fine. Like most all products. You do have to find a sun light protected area for adequate information. I have moved the receiver around inside the house without issue. I also unlike some others, found setup extremely easy.
ADDENDUM May 30 2017 Indoor thermometer still works. Exterior thermometer no longer works. Changed the batteries in both indoor receiver as well as outdoor transmitter with no luck. Do remember changing the batteries once before without problem. Kept the outside transmitter in a maple tree under cover as best as possible. Not sure if having it somewhere totally protected from rain/moisture would have helped or not. I'm thinking probably, but the position I did have it anchored was in a place where rain would not hit it directly. Having said all that, I changed my product rating from a five to a four only because of it no longer working. I would still consider it a four as for 25 bucks, I pretty much got what I paid for and when it was working, I found it to be pretty reliable with the temp and humidity readings. Hope this helps with your decision. Sorry so lengthy.
