## Questions & Answers

**Q: Does the battery compartment screw down?**
A: It certainly dose screw down and, of course, you could superglue it if you wanted.

Personally, I have covered the battery compartment and screw with duct tape so you can't immediately See what’s where!

The decibel noise level is huge. A very neat little gadget for a very low price. So small you would hardly know it’s there.

**Q: Does the red light stay on?**
A: All the time it is switched on the red light will be on.

**Q: On button is very very stiff.**
A: Are you pressing the button or
 sliding it? It should slide sideways. I use my nail with it being small.

**Q: How do you stop the alarm?**
A: It has a switch on the side you turn off and on

### ⭐⭐⭐⭐ Affordable and effective
*by A***R on 30 March 2023*

It’s an effective device that you fit to the door handles. Easy to set up and use. The only issue I’ve had is false alarms due to strong winds moving the device through the keyhole but generally very good. If someone attempts to open the door they’ll get a fright!
