Bests & Worsts Reviews from Amazon

This product will not disappoint you. 120 decibels is no joke. Fire/Police sirens are approx. 120 decibels. Gunshot approx. 140. Most sound charts start the pain threshold at 125. Excellent product and a cheap/simple security measure. Understand this is just an added level of security (like a tall fence, door lock), not an all-encompassing security solution. I'm not worried about amateur/undetermined intruders now. However, now I'm worried about waking the dead... that might be problematic. They're always so angry.
