I already had purchased a Ring doorbell with one appliance ringing in the lounge. I could not always hear it upstairs so bought a second for the landing and very happy with the product. Now I can hear if somebody is at the door from anywhere in the house.

Excellent product. No problem linking it to the door bell. Could be a bit smaller in size.

Works well, easy to connect to the bell and phone. The choice of chimes.

Works well with ring doorbell and you can change the chimes seasonally
