I bought a Kawai ES-110 for my music room to replace a Kawai MP5, which went to another music room, to replace an ancient Studiologic SL-880. I bought it based on the several favorable reviews and my history with Kawai. I wanted a simple piano with a good action to play Pianoteq and Lounge Lizard. The unit is light and feels "plasticky", but once I settled it onto it's stand and began playing, it began to feel great. The action is smooth as butter, and a joy to play. I'm completely satisfied with this purchase. The pianos are up to Kawai standards, and the rest don't really matter, given my reason for purchasing. I haven't tried the bluetooth yet.
