Expert Reviews


What reviewers liked

Simple installation, loud volume, and dizzying collection of 50 chimes to choose from.
This product comes with one button and two plug-in chimes, making it a great solution for two-story homes.
The most inexpensive wireless doorbell.
The volume levels can be adjusted from 25dB to 100dB, which is more than loud enough….although there are louder options.

What reviewers didn't like

Chimes were distorted on the highest volumes levels, and it was frustrating to press the tunes button 50 times to cycle through the options.
No motion and door sensors.
Here is where the SadoTech can be improved. The push button is only rated IP33, which is ok if you live in a climate where you only get a little rain. I would not trust it too much in heavy rain showers though.
