Input: Consider Input: My 3 year old loves this piano! It is so fun and the microphone is a great bonus! Lots of musical options to use when playing with this adorable piano!

Input: Consider Input: I've been drinking these for years. When they changed the formula, it ADDED SUGAR, tastes WORSE, AND often LEAKS. Totally unacceptable, especially for how expensive these are. I've called Gevalia numerous times to try and explain why then need to go back. Seems EVERYONE liked the old formula better. And it was healthier for you. FAIL!

Output: negative

Input: Consider Input: Worked fine for exactly one time of use. Second time I tried to use and didn't start up. Power turned on. It said it was on but never started to come out.
Output: negative
