This little piano is fun for your feet and fingers. It is very responsive and only in the defined areas: keys and buttons. Try pressing outside those areas and you won’t hear anything, but lightly press on them and wow. You can even press the keys with your fingers and they still make a sound. Also, its really cool that like a real piano you can hit multiple keys at the same time. Plus, the weight of the speaker box allows the mat not to slip or slide. Overall, this is a great little piano. Its loads of fun for those who are kids and kids at heart. This piano music mat comes with 3 different modes. The first mode is a basic piano. The second mode is a pre-programmed tunes mode, which switches from “All you need is love” to “Yellow Submarine” by hitting the piano keys. The third mode is a “follow me” memory game mode. Requires 2 AA batteries (not included).
