Pros: Design, Durability, Loudness, Materials, Overall Quality
Cons: None
VERY LOUD & HYGENIC !!!!!!
HAD ONE OF THESE ATTACHED TO MY BOUNCY-COMPENSATOR VEST DURING MY SCUBA DIVING DAYS (1970'S) AND IS EASILY HEARD ACROSS THE WATER TO YOUR DIVE BUDDIES OR THE BOAT....A LOT EASIER THAN TRYING TO SCREAM FOR ASSISTANCE !!!!!!! IF IT WORKS THAT WELL OVER WATER, JUST IMAGINE WHAT IT WILL DO ON DRY LAND ???? SO CARRY ONE ON YOUR PERSON WHEN SPENDING TIME IN THE GREAT OUTDOORS OR CRUISING THE CONCRETE ON A LATE NIGHT STROLL IN THE PARK----------OORAH & SEMPER-FI !!!!!!!
