Not Suitable For The UK
NOT for UK. This is rated 120v not the 240v that you need for the UK. That certainly wasn’t clearly stated on the description when I bought it.

El producto es bueno y funcional, pero hay que tener en cuenta la instalación eléctrica de tu domicilio ya que debes poder conectar tanto tu timbre fÃsico como tu dispositivo inteligente en la misma lÃnea, es decir, tener neutro y fase reales en el lugar a instalar el smart doorbell

Seemed pricy, but what isn’t today. My instalation was putting the wired doorbell where no previous wire existed. Meaning: everything was newly installed. A surprising mounting option for the transformer made the job much easier. I was able to draw power from an existing electrical box by removing a knockout and feeding the load wires through and completing the transformer mounting by attaching the locking nut. This was not an easily accessed area. So the simplicity of the transformer instalation was greatly appreciated.

Compatible with Ring Pro (formerly Ring Pro 2) smart doorbell. It shows up as “Level 1” power in the Ring App. Easy to install and provided 26.5v reading on my multimeter at the front door wires.
