Rock Out With Your Thumb Out
Sure, playing the piano is a great skill and all, but carrying the instrument around whenever you want to practice can be a little tedious, especially with today's high-speed lifestyle. Fortunately, the finger piano makes practicing easy and fun.
You can even use it to put on spontanious performances for friends and love interests and if you're talented enough, the crowd might even be able to overlook how nerdy you look while playing a fake piano that's mounted to your wrist. Of course, no matter how silly you look performing a recital with the finger piano, you'll still look cooler than you would trying to push around a real piano wherever you go.
