The speaker is high-quality and looks sturdy. He has fallen even in the shower and continues to function without problems.
The connection via Bluetooth is really fast and the device is easy to operate. As yet there is no defect, it seems to be really waterproof (not to be confused with submersible ;-)).
Use the speakers almost daily. After showering you can pull it off quickly or simply hang in the shower.
I am very satisfied and can the product.
