SURFOU Multi-Room Wireless Doorbell-1300ft Long Range Waterproof Kit, 55 Chimes with LED Flash, 1 Push Button & 2 Plugin Receivers

GREAT door bell !!! It has so many sounds , some short , some long , 5 volume levels , each receiver can be adjusted seperatly , each receiver has a light , .. push button has a light , easy to set up or change ... very good price , and item !!!

This was so easy to set up and I was very impressed with the range the transmitter had with all three receivers. Nice job, SURFOU!

Super easy to setup and works as expected. Delivery was smooth, no issues. It’s been months since I bought it so far so good. Battery is still going. It has many different sounds to choose from and the sound level is adjustable. This bell ringer was installed at a friend’s apartment. She lives on the 2nd floor and the ringer’s sound is very strong. There has been no lost in connectivity between the outside door bell and the ringer’s sound upstairs. I recommend this door bell.

Works great. Before we couldn't hear anyone knocking unless there was complete silence in the house. Problem solved with wireless doorbell. So easy to install and use!

I have a small condo (850 sq ft) and so I can hear the chime from anywhere. It's loud. I can hear it when I'm on the ground floor. There are many options in terms of the doorbell, but you won't use most of them. It comes with a small 21a/12v battery, tool for opening the case, 2 double sided adhesive pads, and screws/anchors. If you plan on using the screws, you'll need to drill two small holes (just don't drill into the circuit board). I used my own screws that have larger heads so I didn't have to use the 2 provided anchors. The doorbell (outdoor unit) doesn't light up at night. I gave it 4 stars mostly because the unit feels very cheap (but the price was good). It works. Hopefully it lasts and is truly weatherproof.

Good doorbell, easy to install for my top floor and lower level house. Ring tone is loud so you can hear know it no matter where you at in the house.

Amazing performance and sound quality!

This thing is cool. Easy to set up.

Fonctionne très bien

So far so good. Had it for a couple of month and it runs perfectly even though it’s been a really rough and cold winter here in Montreal. I like the sound of it and how it lights up when used. Now I just need the Amazon delivery people to use it to ring when they drop a delivery, I’ve had 2 packages stolen this winter.

Cool! Works well. Nice and loud!

My landlord installed an outer door lock to keep out random wanderers, but no intercom to go with it. I needed a way for folks to announce their arrival, so I decided to try this. All I did to install it was use one of the included double-sided foam stickers to affix it to my mailbox next to my unit number. I plugged the receiver in my main hallway and the doorbell works like a charm, even in the below freezing temperatures we've had so far this winter. I set it loud enough that I can even hear it with the shower running. Everyone from friends to Amazon delivery folks have been using it and it hasn't failed once. There's a second sticker included in case the button unsticks from its surface, as well as hardware to screw it in place if you want it to be more secure, but so far I haven't needed it. There's even a little green "Please ring bell" adhesive sign included, but the bell is intuitive enough that I didn't install it. Pretty good for a $20ish purchase!

Works and loud enough to hear anywhere. Nice to have an adjustable volume. Tones are pretty basic but we just needed a basic sound. Wish it was glow in the dark or lit for night.
