KERUI Wireless PIR Motion Sensor Door Bell Shop Visitor Alert Chime Alarm Burglar

It is to loud for the intended purpose. I wish that I could lower the volume. It has different volume settings but it still is too loud.

Has work well since purchased in Sept 2021 , its now Jan 2022. It has many chimes, I used the simple "ding dong" . Have used the ones from Radio Shack/The Source for years previously they worked ok but found they would ring sometimes repeatedly, annoying. This has been Very good on batteries as well. I will check up in a year.Well, it's Oct 2022 it's still working perfectly!

There is a good range of sounds, and it does all it is advertised to do. Only drawback is after turning off, it forgets what sound and volume you had chosen, so when you turn it back on you have to press through to the right volume and sound all over again.

It is pretty sensitive. It goes off with the Dogs walking in front of it.

Practical and uncomplicated product. Serves our needs quite well and reasonably priced.
