I'll live with the hard resets.

The ugly - 3 stars - the speaker must be hard-reset (hold power and minus button for 10 seconds

The thing is that after 15 minutes of use the app asked me to perform the latest update (which I did) and from that moment on my UE Megaboom failed to stay on and it is just rebooting every 2 seconds, leaving no space for me to make a hard reset or connect to any sort of device, such as my computer, wall charger etc
