Description: A no-spill cup
Main Pitch: "Kids can roll, jump and spin -- and the drink always stays in"
Main Offer: $10 for one
Bonus: 2nd one (just pay a separate fee)
Prediction: Unlikely to succeed
Gyro Bowl was unique and interesting because it applied the "sippy cup" idea to a bowl. This product applies the "sippy cup" idea to ... a cup. Not quite as unique.
Making it look and drink more like a regular cup certainly helps broaden the market beyond toddlers, but the category in general is already quite crowded.
