It's only the bell part of the doorbell, you'll need to supply your own button and transformer, but it works just fine as a doorbell with a pleasant mechanical chime sound.Most importantly for me, it works well with the Unifi Doorbell and the Unifi-supplied transformer. It's easy enough to install if you pay attention to the wiring diagrams.

Friedland D117 Ding Dong Wall Mounted Chime 80db

Very satisfied. Bought this to replace my 36 year old Friedland Ding Dong Chime. It is exactly the same size and the fittings are in the same place no no extra drilling into the walls was required. Positioned inside the front door enables me to hear it clearly. Very satisfied

Friedland D117 Ding Dong Wall Mounted Chime 80db

The chime is disappointingly quiet. Mounted in the hallway, it can hardly be heard in the living room if the TV is on.Four new Duracell Plus batteries lasted only three weeks before ceasing to operate the instrument. Use of the doorbell is normally only once or twice a day - often not at all. This is far too expensive to run.

Friedland D117 Ding Dong Wall Mounted Chime 80db

Great product, replaced one which was really old and broken. This new unit fits easily, works a treat and sounds like the one my parents had in the house I grew up in.Thanks for supplying it.

I now have a working doorbell again.

Works fine but is not a loud as I would have hoped

If you want a loud doorbell try elsewhere.

Looks good, easy to wire up but definately lacking in volume.

Inexpensive and compatible with Nest Hello

It is inexpensive and does the job. It appears to be exactly the same as the D117. I used it with a new Nest Hello video doorbell installation and find that it is the same model as used in the Nest Hello installation guide.

Return it

It just is not loud enough. Probably better with a loud buzzer which doesnt correspond with tv sounds

Suitable for people with good hearing.

Replaced the same type of door chime because it wasnt very loud,I thought a new one would be louder , but it wasnt. Not suitable for an enclosed Hallway. Ok I suppose for a living room. If your hearing is not very good like mine , go for something louder?

Very happy with this.

Exactly replaces old item which had lost it's 'dong ! ' ldentical to old one and works perfectly .Good value item.
