Very simple setup
Excellent product that works exactly as intended. We live in a townhouse so the family room is upstairs. Our doorbell worked occasionally and most deliveries came to our back door which didn't have a bell. This meant we missed most parcels.Enter this AVANTEK setup. Two bells with adhesive pads and one receiver. Receiver is loud and small, set to a normal bell as default and the pairing process took seconds.I got what I wanted and I am delighted. Colour is also pleasant on my grey UPVC doors. Can't comment on battery life as it's just been installed, but it really was so easy to setup and use.

Excellent value
I looked at several similar products and settled on this one because it was attractive in appearance and price. Reviewers also rate the build quality highly. I ordered the doorbell with two ringers, plus a separate ringer as I wanted three. There is no package of doorbell with three ringers. I wanted two downstairs and one upstairs because we were getting fed up with not hearing the doorbell while not close to the front door. Set-up took about ten minutes. The bellpush stuck firmly with the supplied adhesive pad. If this gives out in time, I'll use the supplied screws. It's been in use for about ten days and it's fully lived up to expectations. The signal from the bellpush has no problem reaching the upstairs ringer. Wherever you are in the house, you hear it. You can adjust the volume, and at its loudest, it is very loud. There is also a decent variety of rings. Some of the options are quite useful as they ring for longer. Sound quality is not bad from a smallish speaker. It's not hifi, but then the old analogue doorbell wasn't either, and it's certainly not tinny. Doorbell and ringers look smart too. I can't comment yet on how well the bellpush stands up to weather or how long the whole kit will last.

Easy to install
Not very loud, but works well with a ridiculous number of tones.

Replacement for Grandparents
Perfect for elderly and the hard of hearing, great functionality with so many different chimes to choose from with a good battery light, the doorbell stuck to the door frame effortlessly with the adhesive pad but can also be attached with screws

Great and affordable
A simple piece of kit, reasonably priced and looks dead smart.The plug in part is nice and thin so actually was able to be plugged in behind a unit making it invisible but still easily heard.The push doorbell part is smart, fits nicely and the large adhesive pad looks like it will not be moved.Volume control is great, can be heard all over the house quite easily.The only slight niggle is having to wade through the sheer number of chimes to find something which sounds like a doorbell - I mean come on, how many people really need their home doorbell to play happy birthday or an unimaginable number of Christmas tunes! Sometimes it's ok to make things simple!

Works well
Very reasonably priced and easy to install. You just need to remove the doorbell cover, remove the battery protector, replace the cover and stick or screw the doorbell to your door frame, then plug the receiver into a convenient electrical socket. The furthest distance I have tried between bell push and receiver is about thirty feet and beyond a (brick) wall, but the signal was still clearly received. The default bell sound is nice and loud, and sounds and volume are adjustable.

Better than expected
With so many makes/types to choose from it was difficult to narrow this purchase down. My main requirement was 2 transmitters (bell push) and 2 plug in receivers. I could find this option so settled for 2 transmitters and 1 receiver. I then ordered an additional receiver separately, hoping they would all talk to each other. They arrived in 2 separate deliveries. Both arrived promptly in neat packaging, though there were no instructions with the separate receiver. The installation instructions were OK but the instructions for Transmitter battery installation were poor. Trying to insert the metal key to remove the back cover of one of the transmitter was extremely difficult. I though the plastic was going crack before before it would open. Finally the cover did open. Looking at the battery compartment, I noticed what appeared to be a metal cover over the battery. I assumed you had to remove this cover to release the battery when in fact you slide the battery out from underneath the cover. Pairing the receivers and transmitters was straight forward though I was dubious the the receiver I purchased separately would actually be paired. All worked fine. Volume was very good (I'm hard of hearing). I also tried one receiver in my garden shed and it worked fine. It takes a lot to impress me but these did a very good job. Would recommend.

ADD-ON RECEIVER
The media could not be loaded. This Add On Receiver is a perfect size. I bought it at the same time as the Wireless Doorbell Set. It was easy to set up. Would certainly recommend this little add on.
