Bests & Worsts Reviews from Amazon

Purchased the 1 receiver and 2 transmitter package through Amazon! It's well made, plastic but not to bad! After installing the batteries, I was only able to sync one of the transmitters to the receiver. After exhausting all efforts I called customer service. Again trying to trouble shoot the issue, it was determined that the transmitter was faulty and they are shipping out a new one. I installed the second outside onto my shed to provide motion alert when someone pulled into my driveway or was around my vehicles. Day 1 no problem. Day 2 the transmitted keeps tripping and there's nothing around! The wind is very light and there are no objects moving within say 30-40 feet in all directions around the transmitter. I had to turn off the receiver because it literally sounds every 15 seconds as if someone keeps tripping it. Sorry to say and only due to my experience, I don't think this product is worth it. I will say their customer service was great but for $24 I don't have the time to spend on the phone getting new units! I'll be returning this. - follow up review - after doing some research I found that direct sunlight can affeft the PIR sensor. Seeing that I'm only interested in the unit mostly for night time, I feel it works as I need it. As a matter of fact the second night deployed the unit chimed several times at 4am and woke me warning me that there was motion in my driveway and I found two people trying to break into my cars. They were unsuccessful and took off when I confronted them (I'm retired law enforcement). So to say they aren't working properly would be wrong, they worked as intended.
