Wireless Doorbell. I have started locking the gate to my front deck and needed a bell for visitors and deliverys. I really did not want to spend $40 plus on a doorbell and had been searching the internet for a deal when I came across Light in the box. This doorbell came with two receivers, which I really wanted and could not find. The price and the bargain shipping was so cheap, I decided to give this a try. I am so thrilled. The range is good and at high volume you can hear it all through my house. I have one unit in my shop and one in the house. All for $9.99 and less than $4.00 for shipping. Very, very pleased and will use this company again.
