This little keyboard is great, it's compact so I can take it anywhere I want. The sound (to me anyway) is good, very responsive when each key is press. Their are many features as well such as 10 Song Bank,50 Patterns,100 tones,tempo, and great volume control. It even has a small LCD so you can see the notes your hitting. The keyboard does not come with batteries or a AC Adapter,(I brought this in my JR Music store in NY and they told me next month or maybe in the distant future you will be able to purchase one for it. It takes 6 batteries I don't care for an adapter because I use rechargeable batteries and don't want to be stuck in one place when playing. I'm new to pianos and this will be a very good beginner one for me or even kids might love it as well, but an adult can use it if they don't want to carry a big heavy one with them everywhere they go, The back of the keyboard is orange and the front is black so I really like the colors on it and the design. If your new to pianos (like myself) this is a great purchase for you or a child, its been three days and already I'm playing some of my favorite songs,so get it and play away.
