Perfection in every detail. Well built. Good quality. Seems very durable. The software that comes with it has no flaws,seamless integration with DAWs and hosts. The keybead is very good. Heavy and a little bouncy keys. Just like a real grand piano. My recommendation after 10 years in the business; buy it now. Just remember that this keyboard is a little taller than most. Make sure you have enough space. Also, it is very heavy. About 15kg I think.
