What reviewers say

Reviewers agree it delivers big, bass-heavy sound that fills outdoor spaces, with very long battery life and a rugged build. Both found the fabric surface collects dust and fluff; TechRadar found the app poor and the design unattractive, and Trusted Reviews found it heavy and bulky to carry and expensive.
