Your review: These are very nice megaphones and have suited our needs very well. They are well constructed and very loud. I love having the attached hand held mic, makes speaking a lot easier. They are used in a Law Enforcement setting to address large groups of people.
Pros: Every thing about this unit is a pro
Cons: I wish there had been stickers showing the siren, wail, talk features where the button is. I fixed this by printing labels myself.
