For the price, it perfectly fulfills its function:
To be heard by all! ;)
Needless to push down the volume, like any megaphone, it normally talk but very close to the microphone (the lips should touch the plastic), otherwise beware larsens (very high sounds) that make inaudible what you said ... C It is also why some reviewers consider it as a default, while it is not so: Just make sure you set the volume so that everyone can hear you from far and intelligibly.
A black rubber gasket on the outskirts of the output of megaphone, tends to come loose: So I add a bead of glue in the periphery and repositioned this seal so he could not come off.
Avoid losing because it is useful to ask the megaphone vertically without it is likely to slip.
Despite all plastic construction, it is a device that works perfectly and has the advantage of benefiting from a very low price compared to steel megaphones.
Weight is also appreciated because of light by the materials used.
I am very satisfied with this purchase from its price.
Kind regards,
