Quality Would you consider this product to be made well? How dependable? Very well-made, rock solid. I think the shell is some sort of metal. Features What do you consider to be the best features of this product? What features would you add to this product if you could? The sounds. Full, rich, professional sounds. I'd add a free keyboard stand and bench. LOL!!! Ease of Use How easy is this product to use? How easy is the product to use with other products? Did it take long for you to learn to use this product? Was the manual helpful? How playable do you consider this product to be? You will have to learn the layout first, then it's easy to use. That's with any keyboard. It's playable right out of the box but if you want to explore, you'll need to learn "what" is store "where." I haven't read the manual yet. Sound How is the tone? Kurzweil has always had the best sounds in the business...IMO. Value Was this item an overall good value? Great buy. No regrets.
