Exactly what I wanted! You can turn the chime on/off as desired. I love love love how your phone alerts you! Don’t even think about it! Just buy it!

I love how this small gadget adds protection in our home. The feature that connects it to you phone app is a plus.

Helps keep our family safe. Great price. Works as designed and is easy to install.

Great for being so small. I used it for my window. You can use it on the door as well. It’s very easy to use and monitor.

It is small but noisy. I was complicated to configure it, but it seems that it was my internet problem, the sensor is very good

It works well once it is set up properly. There is a bit of a learning curve to understanding the modes it can respond to, but once done, it is reliable. We used it to alert us if a dementia patient leaves the premises without our knowledge during the night. It can be set for a loud chime with entry/exit, or with a LOUD siren. The siren for sure will awaken the household. It alerts your Android phone anywhere anytime there is an entry exit, alerting if the door is opened or closed. Overall, happy with the performance.

Its small and easy to put up. Its has a app which you can use, it’s easy to use also. I set it up on my front door since i had couple of nights where i seen some random guys walking by at nights. Its been helpful, you get notifications if theres any activity around. You can put on sleep mode while you sleep. Easy set up with wifi.
Liking it so far.
