Review: Super loud. Sense of safety - I have a small child who likes to let herself out unannounced. After a couple times of this I installed these. Super easy. Just peel and stick. On and off switch. Now I don't have to worry about my child wandering off. Also even tho it's not a security system it's so loud that if you were an intruder it would probably make you change your mind about proceeding.

## Questions & Answers

**Q: I am looking for an alarm that shrieks when the door is opened and stops when the door is shut. Is this it? Or is there such an alarm?**
A: Yes, this is the alarm you are looking for.

**Q: Can you set it for a certain amount of time before the alarm goes off? (IE the alarm goes off after doors been open 30 min)**
A: No.  It is simply a small device that has on/off switch.  Works great and is very loud.

**Q: I will be traveling with my husband who has early onset Alzheimer’s. Would this be good to use for the hotel? Does it leave a mark when removing?**
A: They work good. Ive used them when traveling. They dont leave hardly a y noticible residue. If they do. A warm wet cloth will wipe it right up. Have to get some type of extra velcro or double sided tape. Becareful what type you buy as an alternate ahdesive or tape may leave more residue

**Q: Can this be operated remotely ?**
A: No.  It has to be turned off manually, or it will turn off when the battery goes down.I had to manually turn it off. You have to be home to turn this item off. I returned this  item because it can do damage to your ear drums. I  will say I was given no problem with returning the item. I ordered the Bunker Hill Wireless system, and it works for me.

### ⭐⭐⭐⭐⭐ Super loud. Sense of safety

### ⭐⭐⭐⭐⭐ Must Buy
*by B***Z on July 1, 2025*

I purchased this for my father who has dementia, and let me tell you it is very loud and is extremely helpful. When he tries to open the door and wander the alarm makes him alert and he closes it immediately.

### ⭐⭐⭐⭐⭐ Perfect for pool doors!
*by J***S on May 14, 2024*

These came packaged in such a small box. I was a bit worried however, they were individually packaged, were easy to install and are exactly what we need for the doors - alerting us if a small child opened it. This is used as a pool alert for small children and boy is it loud! We mounted it high on each door, so the adult can turn it off before opening the door, but the child cannot access the kill-switch. Perfect! .
