Review on SadoTech'S Wireless Doorbell Kit: 1000-Ft Range, Waterproof And Loaded With 52 Chimes And LED Lights by Mike Maez

So, it seems like a small thing - a doorbell. But ours has been broken for some time, and the wires leading to the button were short to begin with. Over time they became more brittle and it became impossible to get them to attach to a new button. I began looking for an alternative solution. I really wanted a video doorbell so I could receive a notice in my office - which is separate from and behind our home - and to check who is at the front door remotely. But those were quite expensive, and would not allow me to get the back door as well as the front. I found this solution and it has worked marvelously!I was able to program the front door and back door to have different ring tones for ease of identification. I also have 3 receivers - 2 in the house, and 1 in my remote office. The bell reaches about 50 yards from door to office receiver. but that is also going through the entire house. Impressive for such a simple little device. I am well pleased!
