4 Pack Instant Alarms

3 of them did not work. 1 still works. Do not buy these.

Alarms don't work. Either I had a faulty batch or it's so cheap the batteries are unreliable. Either or, my advice is to spend a little more for a reliable alarm.

They do not work

If I could give less than one star I would. These didn’t work at all. And you couldn’t get in touch with anyone from the company.

I needed to replace one of the four (starting using it September 1), and the other three didn’t work.
