Haven’t had to use it but I tested it out in the air and it’s great

I haven't had to use it yet, luckily, but it appears to work perfectly, sounds very strong and is discreet enough that I don't feel like a psycho carrying it around. The safety is also easy enough to flick with your thumb, but still secure enough that it isn't going to switch on or off without intent. I hope I won't ever have to use it, but the comfort it brings knowing I can if I have to is worth the money and more.

Good product, reccomend, fits perfectly in hand.
