Product review (5 stars): Great Little Unit
Got this as a gift for my parents place,they have had it for several months now and batteries have not had to be changed. The Wireless Transmitter has a longer range then expected. Its not fancy but does the job well. It is Nice to know that the battery can easily be changed when the wireless unit as I have had my share of those solar paneled non replaceable  rechargeable battery operated sensors that all were JUNK!
