SadoTech Wireless Doorbells for Home, Apartments, Businesses, Classrooms, etc. - 1 Door Bell Ringer & 2 Plug-In Chime Receiver, Battery Operated, Easy-to-Use, Wireless Doorbell w/LED Flash, White

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 Amazon or local store when the time comes.NO - I DID NOT RECEIVE THIS AT A DISCOUNT OR FOR FREE TO WRITE THIS REVIEW.

We bought the first package of 2 buttons and 2 bells three and a half years ago, shortly after added a another 2 buttons and a bell, then just recently added another button and two more bells. We now have buttons on 3 exterior doors, a button that my Mom keeps with her in case she needs help and a button by the bed in case my partner needs help. We have two bells in each house (adjacent) and a bell for the separate garage. Each button has a unique tone sequence that we programmed all the bells to. While it was a little bit of a hassle cycling through all the tones on each bell to get them set for each of the buttons, the process was actually fairly simple to complete and the bells and buttons have worked perfectly.The only issue I ran into was when one of the buttons was mounted directly to the metal siding by an exterior door, it did not signal all the bells. I moved the button off the metal siding, and now it works. The setup manual actually says that mounting the bell directly on metal siding may interfere with the signal, but I had ignored that initially. Turns out the manual was right.We are using only the bells that plug directly into outlets, not the battery operated bells. The buttons all have a battery, but in the 3 and half years we have had these, we have never had to replace a battery.

For the last year or so my Grandma has casually complained that she often misses visiting neighbors or package deliveries because she can not hear her doorbell from her back sunporch, where she likes to sit. We suggested moving the receiver, but she didn't want to do that because then she wouldn't be able to hear it in other rooms of the house, such as her bedroom, bathroom, kitchen, and/or livingroom. Well when the batteries started to give, and she brought up the problem another time, I figured there had to be a better solution then just replacing them and continuing on with a doorbell she could only hear in certain areas of the house, assuming she was watching TV (which she so often does). So I got online, this product popped up as an amazon favorite with great reviews, and I ordered it.She loves it. She can now hear it ring throughout the house, and the wireless connection is strong enough that even with the lightest push of the button both receivers chime, and in sync with each other. I had worried that with one receiver being an additional 30-40 feet from the remote bell then the other receiver, that they would chime out of sync, and create an awful havoc of a sound if you were in, say, the kitchen, where you can hear both the one from the sun porch and one nearest the front door. So it was nice knowing that was not going to be an issue.Another plus, that she liked, is that these receivers are much smaller, and on plugs. Her previous wireless receiver was very bulky, and on battery power, and she gets a lot of door traffic. At least once a year the two, giant, D-sized, batteries needed to be replaced in order for the receiver to pick up the more distant connection. This is no longer a problem, and she now has both receivers plugged into outlets that are out of sight, as she no longer needs to get behind the furniture every time she needs to change the batteries. She also seems to like the remote button more as well, it's modern, simple, and eye catching; she even remarked this week that her food delivery service, that she has never heard ring the bell before when dropping off her frozen packages, rang it this time.Overall this was a very inexpensive gift that solved a daily inconvenience in an old ladies life, she couldn't of been happier that someone finally took five seconds to solve it for her; I only feel bad it took me so long to think about it.
