Negative Positive
Title: Year Long Test.
Review: I purchased 1 main base and 2 sensors...... and it has been a little over a year since I have operated them. Since there are more Cons: I'll start with them; 1. The alarm is not very loud. 2.The sensors really eat up batteries. 3. it wasn't effective greater than 25 ft. 4.They didn't work well in the cold -- freezing and below.5. One of the sensors appeared as if it was oscillating ..... that's when I trashed it.Pro : It was a good test of my patience !I do not recommend this product.
