I am using this piano for a practicing and in my home studio as a main source of piano sound and midi controller.
In my opinion, it has the best hammer action You can get on a market these days. I work as a professional pianist and keyboard player over 15 years and tried many top end stage pianos from Nord, Yamaha and Roland, So far this is the closest touch to real piano I ever played.
Sounds of pianos are beautifull, warm, just the noise of pedals by factory settings is too loud, but no big deal, you can change it in settings and save the preset. And same with the metronome, by factory settings is crazy loud.
The built quality is great, there are no cheap plastics, but solid metal and wood. The bad thing is that make this piano togather with a hammer action very heavy, I cant cary the piano on a gig just by myself, You need an another person to help you.
Handling is not a strongest point of this piano, but still ok, for expample if you want to play audio file from your USB stick, You may think You put USB Stick inside and press the button USB and find your file, but not,You have to press Record and do some steps to load the song, I had to google it to find out, it isnt intuitive.
Summary it is a great good looking Stage piano, and if you have somebody to help you to carry it, or You use keyboard mainly in studio or home as myself, it is a great choice!!!
