This is an amazing system! I had this up and running in about 5 minutes. Super easy to set up and use. I have a nest doorbell. The camera works beautifully, but the door chime quit working and has never really worked right. I placed this doorbell button right over the button on the Nest door chime button. I can still use the camera, and now I have two working door chimes! One in the kitchen, and one in the basement. I would highly recommend this to anyone looking for a reliable door chime system!

READ the directions PLEASE cause it makes it sooo very easy. Set the Chimes first and the volume level then set #2 chime and volume level. Go to doorbell site and ring bell to know if it works and you are within range of RINGER. Just take out the OLD bell Clean the area and rub dry, stick on the new ! Like ANY adhesive let it adhere for a few minutes before attaching bell. Simple and does NOT have to be screwed into wall unless you want to. There are some reviews you really need to read here cause they really help alot!

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.

Received quick, exactly as described. I read the comments as I needed something loud for hard of hearing parents and this had good reviews. So easy to set up and works great. Even with their loud tv on, they can hear this. If I need to, I can adjust the ringtone to a longer one (like a song) and this way if doing dishes or in another part of the house, they'd hear it and if nearby, they could see the light on it and know someone is at the door. Happy with it. I also like that I can buy other pieces so if I need another plug in unit for a second floor, I can buy one to work with it or if i need another push doorbell for a spare or backdoor or basement door, I can get one.

I purchased the SadoTech Wireless Doorbells for my kids, and let me tell you, it's been a game-changer in our household! No more yelling across the house for them to come to the kitchen when dinner's ready or when I need their help. Now, all I have to do is ring the doorbell, and they come running instantly.

One of the best features is that I let each of my kids pick their own ringer, which adds a fun personal touch to the system. It's been incredibly convenient and has made communication within our home so much smoother.

Overall, a great product that I highly recommend for families with kids or anyone looking for a hassle-free way to communicate within their home.
