Coolqiya Wireless Doorbell Kit, Coolqiya Door Bell Chime with 2 Waterproof Transmitters and 4 Plug-in Receivers for Home 58 Ringtones

Works great in a large house, sounds really good

I bought this product so that my husband and I could call each other for help if necessary. (Two seniors...) Our main first floor is only 1650 sf, with a full attic and a full basement. I synchronized both transmitters to the siren mode, installing the receivers in the kitchen, front and back bathrooms, and the basement. While we can't say why we need help, the siren, set aloud by the person in need, will alert the other that help is needed. (Last week I took a tumble in the front bedroom, yelling for help. Husband couldn't hear me because he was in the rear bathroom with the door closed and water running.) We each will carry the transmitter button on us while in the house. I also purchased two separate receivers - one for the attic and one for the garage. They all work together in sync when one transmitter is activated.

Just moved into a 3,400 SF home where the wired doorbell did not work. Tired a few wireless doorbells, none of which were up to the job. This has a more powerful battery in the transmitter, and it works to send without fail so far, the signal to every corner of the basement, first, and second floors.

These little "Ringers" are really wonderful. We have them placed around the house and one down stairs. We have the front door set on one tune and the back door on another so we can tell which door to answer. The only drawback is that to set them, we had to go through and list all of the rings/tunes so we could line the up to the same tune, there was no list of what order they are programmed. It is a bit cumbersome to set the tunes, having to punch the button and try and keep track of where you are so they will line up, but overall a GREAT purchase. We have even bought a second set to place a few more in places that the bell is a bit soft. I like the expansion capabilities.

Our company keeps the doors locked, so visitors have to ring a doorbell. With most of the company working from home. we are spread out, and needed employees to hear the doorbell throughout a large office. We set up all 4 receivers to one doorbell transmitter, and it works great. We are keeping the other transmitter for a spare.The most difficult part was figuring out why we would set a chime, and the next time we tested, it would be back to the original chime. We eventually figured out what we were doing wrong. The instructions are in translated English.

I have a house with 2 entrance doors. The old-fashioned doorbell chimes I had could not be heard on my 2nd floor. So, I needed a system that could indicate which door location's bell is being rung (by programming different melodies), as well as being able to locate sound-generating receivers on both floors of my house. This system meets those criteria. Good system. The supplier's company (Coolqiya), and their Customer Service Representative, Yuan, were very courteous and prompt with their responses to the several questions about programming I needed to ask. I highly recommend this product because of its flexibility and versatility.

I might have misunderstood the loudness of the doorbell but in general it isn’t that loud. It’s nice that you can set up on different spots.

We use this as call buttons for my disabled mother. She had a series of severe strokes that left her unable to walk or talk. These have given her some security that she can call for help. It comes with two buttons so we have one in the bath and one loose to carry room to room. They have been immensely helpful in caring for her and giving her a voice. Easy to setup and the instructions were simple to program different “rings”.

We had another wireless doorbell system that rarely worked. Deliveries were being missed or dropped at the business next door. This system never fails and works so well. The receivers are in various spots in the building and can be heard anywhere in the building. The receivers are programmed for a different ring for the front and back door. Highly recommend this product!

We are using this doorbell kit on 4 separate floors. The bell adheres to the outside door in winter, and the ring is very audible on all floors. A great product.
