Review on Ultimate Ears MEGABOOM 3 - Portable Waterproof Bluetooth Speaker in Night Black (Bulk Packaging) by Alexandra Johnson

Excellent sound and bass. Bluetooth is great. The battery, however. DO NOT charge this item. This will fry the battery. Otherwise the thing won't break. Virtually indestructible and resilient (won't scratch, scrape, tear or dent no matter what) and has settings you can tweak with the in-app audio mixer. I personally love this speaker but had to get a new one from customer service because overnight charging burned out my battery (DO NOT DO THIS). If you charge it for 30-45 minutes, it's almost 100% (sometimes it takes time when dead). Great for camping, sports, the beach, old cars without bluetooth (yes I do sometimes lol) and just about anywhere you want to listen to music. I can only recommend it👍
