Battery life is pretty good and it’s been awesome for work. Battery life: I’ve only had to charge it once since I’ve had it in about year of light usage. Functionality: The Bluetooth and sd card option is awesome. Value for money: For the price it’s great value, not as high quality as far as materials but it’s still working for me. Sound quality: Solid quality and very loud. Durability: This is where I wish it was more harder/sturdy plastic but it’s been working so far under rough work conditions. Review: Great Volume and Clarity - This is needed to use out of my upstairs loft's window (without being seen), to initially, politely ask the out-of-control, homeless, substance abusers screaming and fighting at all hours in the park across from my loft in Portland, Oregon, to quiet down. The volume and clarity of the megaphone is excellent, but my request is not always met. ## Features - Powerful And Multipurpose:MGROLX PRO MEGAPHONE can provide up to 50W and 1500 yard sound which is specially designed for group and outdoor activities, such as sports activities, political demonstrations, social management and cheerleading activities.
