Review on Hztyyier Emergency Rescuing Survival 80 130DB by Brian Olson

This thing is awesome! It's light, so it feels really strong. Oh honestly it's f@#$%÷+ LOUD! I blew harder than I expected in my wooden dining room, and my ears rang afterward. The low profile makes it quite unique, which I really like. This is a great addition to any keychain that, like me, uses brass primarily to decorate their EDC set. For the price you get some really well thought out noise canceling technology.
