When we moved into our house, the previous homeowner had taped off the home's doorbell since something went amiss with the electrical wiring of the one that was installed. For months, we didn't have a working doorbell, and we had to endure loud knocks on our door. I wanted to get this fixed ASAP, and had an electrician initially give me a quote to get the wiring back up to snuff, but I didn't want to spend the $140+ that he priced for the fix, so I found this SadoTech wireless doorbell on amazon, and it solved my problem at a small fraction of the cost. I was impressed that this doorbell comes in various colors, and at a little over $20 (I purchased the white one), I felt like a genius seeking out this solution to my lack of doorbell issue. I have an awning over my front door, so I can't speak to the longevity of this item if left out to fend the weather without any protection, but ever since we installed it months ago, it is still in tip-top shape, and the sound is very effective and just what we needed. I couldn't be happier with this product!

I read both good and bad reviews about this product. Unfortunately, I read good and bad about every single of the many wireless doorbell options available and I had to get one. This product had a better good to bad ratio on reviews, so I bought it. Very reasonable price too. My home's original doorbell is old and pathetic, and I just moved my home business into a remodeled basement where I couldn't hear the doorbell at all. I have one button on the front door with a doorbell unit upstairs and one downstairs. When the button is pushed, they both ring. I have the option of tow different sounds if I so choose. There are some silly song sounds that some may like, and although I wouldn't mind more bell/ringer choices (variety wise), there are many to choose from. There are also four volume options. I have found that the third highest is easily loud enough. My home is not very large (about 1400 square feet), and both bells are about halfway across the house from the front door, and reception does not seem to be an issue. Some people have said in reviews that they had less performance after a short time, but I have had this setup for a few months and it has been working fine.

I bought this for an older house to replace the nonworking "wired" doorbell.
It literally took me 1 minute to install.
Plugged in the door chime receptor, by the kitchen, took the tape off the back of the door bell button & stuck it to the front door casing.

WARNING! Make sure the button is exactly where you want it. I changed my mind and wanted to move it 4 inches lower. It was so secure, it pulled off some paint. But that's on me & I touched up in a minute.
Nice "Door Chime" sound heard loud & clear.

This is my first ever product review,but I think it is important to share how well this door bell has worked as a call button for my 94 year old mom and me. We live in a rather large house and I go outside alot ( so the portable unit is very useful) . With this door bell she can let me know if she needs help. I have finally been able to get some sleep at night.!! She is very frail and speaks very softly, and she also listens to th t.v. at a super high volume, so the baby monitor did not work....I heard the t.v. all night and not her. The bell sound is very , very loud and clear. The button is a good size and to put on a string, so she wear it around her neck, and it helps it not get lost in the sofa cushions. Both the button and bell units are a good quality plastic an feel well made. I hope this helps someone that does not want a monitor sevice, but needs a call button.

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. I PAID FULL PRICE LIKE EVERYONE ELSE.

I AM DISAPPOINTED IN AMAZON REVIEWS LATELY BECAUSE MOST REVIEWS ON THE FIRST PAGE ARE FROM PEOPLE THAT WERE GIVEN THE ITEM FOR FREE OR AT DISCOUNT IN RETURN FOR A REVIEW. AMAZON SHOULD HAVE A DEDICATED SECTION FOR THESE PAID REVIEWS.
