## Customer Reviews

### ⭐⭐⭐⭐⭐ Fantastic!
*by V***E on 14 December 2023*

So happy with this gadget. We bought a Ring doorbell in our old house that wired up to the main doorbell, which was grand and perfect. Then when we moved there was no in built doorbell so we was really disappointed with not being able to fit our doorbell here.A few months later we found this option, so we purchased it, not expecting any result, but was so, so happy to find that it works perfectly, it was a fantastic price and as yet we have none of the issues of buzzing that have been mentioned in other reviews.

### ⭐⭐⭐⭐⭐ Works perfect
*by M***D on 14 April 2024*

Much cheaper than the branded item and works just the same! No issues with the humming at all as mentioned in some reviews! Plenty of length on the cable

### ⭐⭐⭐⭐ Easy and simple to install, but a bit bulky
*by D***D on 20 March 2024*

So this is very easy to install and absolutely does the job. My only comment on this is that the transformer is quite bulky.
