Noopel Door Alarms 6 Pack for Kids Safety, 120DB Pool Alarm Sensor for Doors and Windows, Burglar Intruder Entry Alert for Toddlers Personal Security

I am pleased with these alarms. They are very easy to install and use. I also like they had an option to buy them in a larger quantity to save money. The price was decent also. I am probably buying more.

The alarm is easy to install and creates a loud alarm when doors are opened. Total time to install was 30 seconds or less and no hardware or tools needed. This was perfect for adding an alarm to our doors leading out to our pool area. It prevents small children from going out to the pool without your knowledge. Highly recommend!

For how tiny this thing is, I'm impressed by how loud it gets. Literally turned it on when I first put the battery in and my ears starting ringing. It's incredibly loud.I highly recommend this product! My only complaint is that you need a door that sits flush with it's base for this to work. I tested it with a door that doesn't sit flush with the base and it worked fine initially. However, after I opened the door and closed it again, it didn't sense it. However, when I tried it with a door that sits flush with the frame, it worked perfectly!Overall, with the price it's selling for and with it's quality of work and loudness, I definitely recommend this product. (my ears are still ringing as I'm writing this lol)

I LOVE these. I just wish there was a delay so every time you turned them on, the whole house does not know. If your objective is to catch someone, no one can be around when you turn each one on.BUT..... It's a GREAT product

Very loud perfect for it's purpose
