## Questions & Answers

**Q: Will it trigger if the intruder breaks the window?**
A: Not unless the sensor happens to fall off during the break in. It's not intended to detect breaking sound.

**Q: Will it work in a metal mailbox?**
A: Yes I can see that working.

**Q: how do you get the cover off?**
A: Either with finger nail or a small flat screwdriver. It comes off very easy.
I love this switch. Already there are three in my townhouse. After changing the battery, it starts working with no set up needed.

**Q: Can you set timer on these devices to not activate? Ex: if use on window, there are times in the days i would like to leave the window opens wo alarm**
A: So far I have not had an actual alarm go off at any point. It does however keep track of when the door is opened and closed I am sure that if you leave it open and an alarm goes off it will be able to be desmised by your phone.

### ⭐⭐⭐⭐⭐ good value

easy to install, works great , good value

### ⭐⭐⭐⭐⭐ Sensor works great.
*by C***S on August 16, 2025*

Great door sensor. I have the older model on my mailbox. I'm sure this newer model will work just as good.

### ⭐ Waste of money -- doesn't work well with uneven doors - stopped working after two months
*by L***K on May 31, 2023*

I'm further updating my review because these completely stopped working now. It's past the return window too. They're a waste of money. I'm updating my review because now these are working only sometimes, or I'm getting an alert a few minutes after the door is closed again (some weird connectivity issue maybe?). I got them so I'd know if doors were opened and dogs were getting into the street. I need to know that immediately, not two minutes later, and I need to know 100% of the time, not just "most" of the time. They're frustrating. I wish I had gotten something else. These are okay. I got two. My older house has doors that aren't flush with each other, and the device requires a gap of less than 0.7 centimeters, which is pretty small. I was able to add a large block on my door to make them even enough to work, but it looks clunky. I wish I'd realized before I bought them that they needed quite such close contact. However, these are my first contact sensors, so maybe this problem is consistent with all devices. The instructions are minimal and miniature.
