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

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.

I bought this door bell because my door bell died and I could not for the life of me figure out where the actual chime box for the original door bell even is in this house....of course moments after I bought the new bell my husband pointed it out to me (DOH!). No matter. I'm not an electrician, nor do I want to monkey around with the chime box or buy a volt meter to diagnose it's problem. Whateve's I knew I could just click one button on Amazon and have a crazy easy solution to my broken doorbell problem (both bells are not working, hence the conclusion that the problem is in the chime box) ANYWAY, I did my one click shopping and shazam, two days later the new bell is on my doorstep. I even used the old screw that already had the anchors drilled into my brick exterior. Both screws did not line up to my former classic doorbell, but it's so tight that bell isn't going anywhere. The box came with 2 plug in chimes. I tested it on a plug closest to the front door first and it was nice and loud...though apparently I can change the chime, I'm not picky. Then I took the plug up to the second floor to plug it in there to see if the radio signal would work. In case you think that's crazy this is an extremely old house....like 150 yrs old with 10 inch brick exterior walls and very thick plaster inner walls. Even our doors are solid wood. I don't even get cell phone signals unless I'm standing next to a window, so I was a bit concerned. No matter where I put the chime it worked. So I have one plugged in near the back of the house (near the television and kitchen fan noise) and one plugged in at the 2nd floor landing. All of this took mere seconds. I'm sure it will take me longer to find the wire cutters to disconnect the old door bell.

I was very hesitant on investing more money on a 'doorbell' as I had tremendous bad luck with two doorbell systems at Lowes with a different manufacturer.While searching Amazon.com for their inventory of doorbells, I really was drawn to this one. First, it was easy to install. And second, it really appeared to be a reliable doorbell system as it was dependent on a battery (the transmitter/actual doorbell), and electricity for the (receivers/sounders).I installed it all by myself, and I'm very challenged with 'handyman' skills. So, it's very, very easy to install. But what I like most of all, it works! And it works fabulously! It doesn't short out like the other brands at Lowes as those other brands were dependent on a 'signal to a signal' in order to produce a sound.Many neighbors, family, friends, and customers are very happy that I have installed the new Sado Tech Model CXR Wireless Doorbell because it WORKS. I know when someone is at the door and I do not miss their visit. And it's plenty loud. I have one receiver at one end of the house and another at the other end of the house...I do not miss a visitor at all!This doorbell has many wonderful doorbell sounds. You pick the sound of your choice, but if you have an electrical trip/serge the doorbell automatically resets itself to the 'Ding Dong' sound. That is still so wonderful because you'll still know when someone is at the door. When you have time you can reset the sound of your choice.I wish there were more 'styles' to choose from as I have a beautiful country home and the doorbell system is modern looking. But I'm truly happy that it is a very reliable doorbell system that is very easy to install and maintain...very easy!
