Super

Buzzes a bit but not noticable

It does work with eufy doorbell the only concern I have is a bit noisy

It does exactly what it's meant to do and works perfectly with the ring doorbell

As per other reviews, this worked well for a month and is now has a loud humming noise at 2am and feels quite warm. What I hoped to be a medium term solution has cost money and I still need to get my doorbell wired properly soon as this cannot go on. Very disappointing.

Sent back as not working, supplies just above zero power so will registered as wired, but will not charge, even when all functions off your doorbell are switched to minimal power. I have not given one star as this is probably just a faulty item or batch.

Worked as it should and delivered promptly. Not it doesn't have the crimped rings on the end like some do, but they are soldered together so wrap around the screws well. Also easy to push through small holes etc as just the cable. Decent length too.

Excellent works well with Google doorbell
