I love this doorbell. The outdoor unit has a battery that is supposed to last 3years. It just screws to the outdoor wall. Then you just plug the 2 indoor units (the chimes) into wall outlets. Works perfectly.

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!

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.

We use this doorbell for incoming deliveries in our warehouse, and it works perfectly. The range is excellent—it rings all the way in the office. Easy to install, and the chimes are clear and loud. The only drawback is that the doorbell button is kind of hard to find.

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!

Funny enough I did not buy this for my front door but I am sure it would work great for that. We live in a multi story home and sometimes its tough to call the kids down without having to scream up the stairs. So we keep the button on our fridge and my kids have the other end upstairs so I can buzz them down when needed. Its not super large but easy to spot with bright lights and an adjustable volume. I haven't changed the batteries since we started using it ages ago and its still going strong. Great doorbell for those in need of one.

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.
