Works very well. You need to be careful when changing the battery as the plastic is a bit fragile. Unfortunately, it doesn't have a low battery level indicator. You have to change the batteries from time to time without having any information or testing with the button.

I have been using these detectors for a couple of years. Now I have bought more for other projects. They work very well. If the red LED flashes quickly, it indicates that the battery is low. You change it and depending on usage, the battery lasts more than a year. Recommended for alarms at 433mhz. I use them with a hybrid home automation system of my own design.
