Review on Wireless Doorbell For Home - Long Range Battery Operated, 1000 Feet, LED Flash, 1 Button + 2 Receivers, Matte Black Finish By SadoTech by Mark Williams

Perfect for our needs. For a few dollars more I got the model with dual doorbell receivers and one doorbell button. Arrived in two days (Prime). The chime receivers are smaller than anticipated but are plenty loud. They plug in so I do not need to worry about replacing batteries, but does limit where you can put them. Our house is two stories and my home office is upstairs in the far bedroom. I was going to put one in my office but found the unit I put in the livingroom, near the front door was easily heard in my office. Plus it can be heard by the person ringing the doorbell - I hate it when I ring a doorbell and do not hear it. then stand there wondering did it ring, is it broken, should I ring it again? I put the second receiver in our family room/media room. We watch a lot of movies on our big screen with volume fairly loud. With the second ringer in that room, we can now hear if someone is at the front door.I had everything hooked up within 5 minutes of opening the box. The front door button comes with a battery, just pull the tab and it activates. You can use the double sided sticky tape included or drill holes and use the screws and anchors included. I used the sticky tape and placed the doorbell on a rough wood frame just to the right of my front door. It stuck very firmly. I have a covered entry, so am not concerned with it getting wet.Setting the ring tone took the longest. My wife and I cycled through all 50 tones before settling for ring #2. A standard doorbell sound. If you unplug the receiver, it defaults back to the first ring tone - a standard ring. Same happens if you have a power failure. So if you picked ring #37, you would have to cycle through all the rings to get to #37. Inconvenient but not devastating. Going with ring #2 keeps it simple.The range seems very good. The signal reaches our family room which is in the back of our house and has to travel through a couple walls.The doorbell button is attractive - high-tech looking, unlike many others I looked at. I don't know why these wireless doorbell designers don't put more thought into the button. After all, it is part of the decoration of your home, just like a porch light or door knob. This is one of the better-looking buttons out there. The receivers are also nice looking. Like I said, much smaller than I thought. I was able to plug into the top receptacle and still use the bottom receptacle to plug in something else - although, it is a tight fit, so depends on the size of the plug you are using.Pros: Very easy to set-up and get it working. Nice looking. Loud (has 3 settings). Lot of ring tunes to choose from. Small. Excellent price.Cons: Have to cycle through 50 tunes. Does not have memory to remember your tune selection in the event of unplug or power failure. Battery in the doorbell button is not AAA and will have to be purchased on revain or local store when the time comes.NO - I DID NOT RECEIVE THIS AT A DISCOUNT OR FOR FREE TO WRITE THIS REVIEW.
