It's a very addictive experience and is a lot of fun to use! It just sucked me in to keep playing and experimenting with it. I was using a prototype, but can't wait for the production versions! Awesome gift for the Holidays coming up!
The app can be used without the device to get a feel for what it would be like without the instrument, and there's also a version for iOS devices that uses Bluetooth Low Energy on the iOS App Store (launched in August).
