Now the benefits to other cheap models:
1. No one can simply change only the toggle switch to turn it off.
2. The battery is available with 2 AAA batteries what others offer only with button cells.
3. Alarm turns on when you go away from home, the other models can not also also.
Here are 2 types of modes possible.
If someone opens the door slams it off immediately, or after a delay of about 10 seconds what else for a
some time leaves the alarm off.
4. Operation Child's play.
5. Now I just test how long is keeping the battery. The battery is the way bolted, another advantage for the burglars
can not remove the battery equal. Surely that is a bit complicated for the burglar and a shock moment.
6. It is boring with or with adhesive strips to attach to the door.
7. Our neighbor is not easy again einspazieren times.
Have fun and do not depend on the other reviews, that's the truth, and the thing works! Properly.
We have ordered our balcony and entrance door.
