In order to be heard at a Fasnetsumzug, I have gained this "gem". Relatively good workmanship, but all in all you realize the price of 29 rather clearly. The volume control is very inaccurate (slider) and the button "music" plays a time very annoying "Ole Ole ...". The advertised shoulder is only a very small and sloppy processed loop that was already broken after about 2hours wearing. Another shortcoming is the extremely high weight if the megaphone with 6! 1.5V mono batteries loaded. The mitgeleiferte extra microphone also acts processed rather cheap and the cable connection to the phone jack (3.5mm) is after a single use and battered already properly. My conclusion: you get exactly the processing corresponding to the price! If I ever again order a megaphone, I would to higher-priced models to grab a minimum level of quality to be able to presuppose.
