Query: Love the bluetooth; Really disappointing keys

Had to return. The smaller than normal keys along with poor (to me) key feel made this a bad choice for learning to play. The bluetooth was convenient in many ways, but annoying in others - a cable is easy to just plug in while the bluetooth requires you to connect to it from a compatible app before it's available. (Once you connect via an app, it's available to all apps even if the others don't have an interface to connect to bluetooth LE devices)
