“The quality of this lid is very obvious and seems like it will last for years to come. The overall design is very clever and clean with the highlight being the tab that you can depress to seal the lid and easily release. Gravity is the only downside of this cup design, as filling it up to the top will still allow the weight of the liquid to escape (dribble) through the flaps made for the straw but that is a small price to pay, in this satisfied customers opinion, for a multi-functional lid with such a cool design! We will definitely be buying from this company again. Adult Sippy Cups FTW!!!”
