SURFOU Wireless Doorbell with 3 receivers 2 Buttons,IP55 Waterproof Doorbell,1300 FT/400M Remote Doorbell,55 Chimes 5 Volume,Colorful LED Flashing,110 db Loud Volume,For Home/Classroom

Multiple chimes can be placed strategically around the house so that you can always hear them. And the flashing light on each unit helps in case you don't (or cannot) hear the chimes.Having 55 different tunes from which to pick is great, but keep in mind that the speakers in the receivers/chimes are fairly basic quality. This is true of most of the various wireless doorbell options that are available. So as much as you may like, say, "Jingle Bells", you could quickly get tired of hearing it.To me, one of the best features of this product is that it will "remember" your chime selection (separately for each receiver) if a unit loses power. It would get tiresome to re-program each receiver for every occassional short-duration power "blip", which is common in many locales.My only disappointment is that the VOLUME setting is NOT retained on the receivers when power is lost. I reported this issue to the seller and found that their support is absolutely top-notch! They responded to me in less than 12 hours, requesting more info. I sent them more detail, and again they were quick to respond. They tested and verified that the issue does exist, notified the factory of the problem, and immediately updated the product descriptions on Amazon to remove any references to saving the volume setting.

Works great and it's was as described.

For the money, this kit is quite the bargain. The basic setup is straightforward, but assigning a different ring to each transmitter isn't covered in the instructions. I managed to figure it out, but it's not specifically covered in the booklet. Also, if attaching the transmitter with the double-sided tape, it's not necessary to use the whole tape, only the vertical strips and screw dots. I think it's a cleaner installation that way.

I take care of a building that's only partially occupied which results in staff not being near the front door to greet visitors. Adding this doorbell will allow all of our staff throughout the building to know when someone needs to be let in.The cute little "Push button" signs were a nice, unexpected inclusion.

We find them to work great- front has one ring tone and the back has another

Arrived timely. Works great.

Great little doorbells... just talked a bit to figure out how to set them.

This was exactly what I needed. I replaced our front door bell button and also needed a button for my shop which was 100 feet away. I was a little concerned it might not work but it worked great. I now can tell if someone is at our front door when I'm working in my shop. Very happy.
