Query: Worst Product Ever, Total Waste of Money! Don't Buy It!!

I bought this as a Christmas gift for my husband. Due to it arriving in winter, my husband was not able to set it up until spring (when the return time frame had ended). He was never able to get a signal at the receiver in spite of hours of varying the placement of the sensor. I wish I had read the other unfavorable reviews prior to purchase, as I never would have bought it. I gave this product 1 star as I was unable to to change the rating to a zero...is that a strong enough statement?! Don't buy!
