"This speaker is overall great in terms of sound, 7 hour battery life, light and sleek, waterproof, but removing one star because it doesn't freaking stand up without falling over due to the way the base curves. Who would design it like this?? Almost perfect and not regretting the purchase but that one point is super lame"
