This Auna Rocketbox 2.0 Mini Bluetooth Speaker with battery and radio is really great !!! The sound that produce the small speaker is clean, simply good. The box itself is well made. Only what I bemängle is the Bluetooth connection, the tears, though the distance was only 2 meters between Auna Rocketbox and laptop. But it may also be due to the transfer of our laptop has yet to be clarified !!! Otherwise, the device is highly recommended !!!!!!!
