I use it for four months. I use it for home studio recording my songs.
Before I used my pc with software adapted but I found it too "gas factory". The micro br greatly simplified my life because it contains everything I need to create my compositions.
Being able to create his arrangements of batteries from existing patterns is a real plus.
The microphone is very good. I do not use multi effects section as I plug the output of my amp directly emulated on the micro br. The realization of the compounds quietly without taking his head with vst software and makes it an excellent product.
It is certainly not easy to take control early because of the number of functions and therefore the limited number of key date, but after some time, the navigation becomes very intuitive.

My only regret is not having bought sooner.
