I was very confused on how it worked as one had a box with instructions and the other didn’t, luckily I bought 2 .. it’s loud you must pull the thing on the top out for it to work, keep these instructions in a safe place or u will be scratching your head, lights work , be careful as it is in my bag and half of it lifted up so I had to snap it back together , overall not a bad product for the price it would deter someone as I said it’s pretty loud

This works great you just pull out this button and the sound is pretty loud then you just push the button back in to stop it. It’s also has a little flash light that also blinks. I plan on buying another one for my other grand daughter to put on her keys as protection.
