Intelligent Welcome and Greeting Warning Doorbell Sensor Bell Alarm Door Chime Bell Entry Alert Entrance Alarm for Market, Closer to Lives of Consumers, Office Buildings, Shops, Factories

I needed something in my office to let me know when someone walked in. This did the trick. Simple to set up and sensitive. Loud enough to hear down the hall (about 20 feet).

Arrived quickly. Easy to set up and install. Very effective at letting me know when someone enters my office. Able to quickly change volume and ringtone. Small size is convenient.

This bell works well although most of the available sounds are quite annoying. I wish that it had a simple bell, I have not been able to find it if it is there. One fault that I have found is that the bell sounds off when a door opens, and when it closes. If it had a delay so the bell only sounded once it would be better.

This thing is defective, worked good for two days then stopped working

We got this to use at our dog grooming salon. To let us know when someone comes in while we’re in the back. It works great.

I bought for my store as door bell. It sounds good; but at times, it chimes continuously, annoying everybody.I wish to return and try another one.

Now my boys won’t scare the crap out of me I’ll be able to know they are coming!Bing bong!

Worth every penny! We use this to let us know when our blind and deaf dog gets up in the middle of the night. Works great!
