Best value for your money
These are definitely loud enough to hear throughout the entire house! The adhesive is strong too as I had to readjust a few a couple of times and they are still sticking

Some work some don’t
3 of them didn’t work on the window. They would only work in my hand. Weirdest thing I tried everythingBought a 5 pack earlier they worked perfect

Easy to install and LOUD!
These alarms are super easy to install and they are LOUD!!! I use them on my windows but they’d also be great for pool alarms.

Mark McAllister –
Not good
Very poorly made. Took the battery cover off and it would not go back on correctly.

Great buy for budget security!
Love these alarms. Great bang for your buck if you need added security for yourself or for little ones. Buy batteries separate as they are not included. Great battery life has lasted us now for 3 months. Security is very reliable with these alarms. Pretty loud for what I need them for. Function for everyday family life. Easy to install to designated area:

Bang for your buck!!
If you need to cover a lot of entrances in your home… this is how to do it. They work just like the expensive Phillips brand at a fraction of the cost. I like that I have enough that I have a few for back up. Makes me feel safe!
