Title: For the money you cant go wrong
Review: I used this devide to track the coming and going of a skunk from under my front porch. I tried to trap the critter for weeks, but with the sensor I was able to confidently seal off the passage way he dug, preventing the return of the anmimal. I now utilize the sensor to tell me when I have someone at my door until such time as I can get the doorbell fixed. I am most pleased with the utility and value of this item.
