Despite several updates, still very buggy (restarts to do, responding) The smartphone control application is one of the most poorly designed that I had the opportunity to see (plant, difficult navigation, not ergonomic) Operation from a computer not documented in the manual. possible but very galley also plant The sound of the built-in amp is ok but not enough to obscure the misfires of the design. Too bad because the ergonomics and control works could have done a good device. Avoid.
