All of the following AVANTEK doorbells with plug-in receivers can be paired with each other: CB-11/CW-11/CB-12/CW-12/CB-21/CW-21/D-3B/D-3W/D-3G/D-3F/DB-21 (For orders purchased before 2021, it is best to tell us to inquire whether they can be paired.)
Long Operating Distance
With a reliable wireless range of 1,000 feet and strong signal penetration, the doorbell will never fail to alert you when someone shows up at the door. Enjoy a reliable and hassle-free doorbell system at home, in factories, offices, classrooms, apartment blocks, villas, and other large areas.
Convenient Size
After carefully researching customer feedback, we have upgraded the design of the receiver station, giving it a smaller size of just 2.8 (L) x 3.1 in (W), so that it won't block off any neighboring power sockets.
IP55 Waterproof
IP55 waterproof and functional between -4 °F to 140 °F, the doorbell can operate in even the harshest weather conditions.
Music to Your Ears
The doorbell boasts an ample selection of 52 melodies from traditional doorbell chimes to jingles, certainly offering a chime that suits your taste.
Mute Mode
The silent volume level doesn’t disturb a sleeping baby and the maximum level of 115 dB is hearable by the hearing-impaired or even during a party.
Memory Function
Thanks to its smart memory function, it remembers your previous set melody and volume level - even after a power outage.

Reviewed in the United States on September 25, 2023
I ordered this specific set because I have a large house with a front and back door that are both commonly used. The biggest benefit to these is the ability to set them each to a different sound. Now, when I hear the chimes, I know exactly which door to run to. My house didn't come wired for bells so I knew wireless was the easiest option and these were some of the least visually obnoxious that I could find. Many of the doorbells that I saw while shopping appear designed for alien spaceships with lights and weird shapes. These are just noticeable enough that people realize you have a doorbell.
I really wish that AVANTEK would offer a set of two remotes with a battery operated receiver. I was torn, when ordering, between this set or just getting two battery operated single remote and receiver sets. I went with this one as it was the more economical option, but I’ve regretted it. The issue that I have run into with this set is that having it plugged in all the time means that it gets in the way. I wish I had the option to put the receiver somewhere truly out of the way. Additionally, the chimes aren’t always remembered. When the receiver was unplugged to move it from one outlet to another after initial programming, it forgot the chimes that were programmed for both doorbells. Although, later, the receiver was bumped and knocked out of the outlet and when plugged back in, it still remembered the chimes. A final time, the power went out for over an hour and when it came back on, the chimes were still remembered. So it seems to be fairly hit or miss. Another consideration is that when the power goes out, your doorbell won’t work. While this is true of wired doorbells too, the battery powered options don’t have this concern. If you live in an area where you have common power outages you probably want to consider looking elsewhere if you plan on having visitors during storms.
One final note, is that after having these up for over a month, one of the remotes has begun to yellow slightly. This particular remote gets full sun for about half of the day and has been rained on an awful lot. I’m not too upset about it considering the conditions that it sits in, but it’s something to keep in mind. The other remote, which is placed on a door that’s covered by a roof, hasn’t yellowed at all.
Overall, I would recommend this wireless doorbell set as a great, affordable option that doesn’t draw too much attention to itself. If you’re not on a strict budget or if you live in a home with limited outlets, I would recommend spending a little more for the battery powered option.

manual metal door knocker system for visitor announcements. Now authorized people that
are visiting simply press the external ringer button and I instantly receive a warm sounding
chime notifying me that someone is at my front door. There are several musical tones to
choose from and the volume control is adjustable.. The installed battery is still operating
well and the overall signal reception is good.
I recommend this product for those that want to customize their door bell system experience.
Good luck!
The end result is a highly recommended product bar none period !
Top reviews from other countries
This model comes with 2 receivers - I have one on each floor and I can finally hear the doorbell when I am upstairs.
Was very easy to pair the receivers and transmitter - I was concerned about that but not an issue at all. The tone I have chose is loud enough.
I like the fact that you can switch the sound off completely if you need to (has a few loudness options).
Cons:
The only con I would say is that it says it comes with 52 chimes, but there are only a couple that I consider actual doorbell sounds. I takes quite a bit of time to find a decent tone and I had to do that for both receivers. However that was a minor con since there are so many pros.
Most of the chimes are horribly annoying, but it has a mostly normal ding dong sound which we use for the front door and picked Under the Sea (from the Little Mermaid) for the backdoor which doesn't get used very often.
I used the adhesive to mount the buttons which is fine for the east facing back door, but the one on the west facing front door fell off in the afternoon/evening sun so I had to screw that one in place which was easy enough, just don't overtighten the screws as it will slightly bend the base inward which can prevent the button cover from snapping into place. The volume is great, we can hear it clearly from anywhere in the house/basement.
Would recommend this to anyone looking for a wireless doorbell with two buttons that can be set with different chimes.
