A fantastic musical instrument. I can't find any real "cons" about it, just a very few things on a "wish I could list". However you won't find any of the withes on any other similar instrument.
I am thrilled to have it. A long learning curve and you really have to use "youtube" for the best teaching source. Some very good ones.

The clavanova 809 is unbelievable. It does everything you could ever want as a piano and more, pop down to Keysound and ask for a demo, they will only be too pleased to help.
You wont want to leave without one.

Just bought a CVP 809 for my vocal studio. Love the Piano Guys. Highly recommend!

Plenty of features to keep me entertained for years. Sounds great, and with the headphones on it's even better. Love this piano!
