Nice speaker for on the road and on vacation. Nice sound, sturdy and waterproof. Due to the minimalist design it is sometimes difficult to find certain functions (e.g. battery level, connected devices)

It is exactly what I expected for the price. A small box that is easy to carry and gives a very nice sound
