I didn ' t care for it . <| sep |> What an awful design compared to solo traveler like lids . Never mind that coffee spills out of a top where all the sides are enclosed , now you have a version that doesn ' t have the structural integrity to create a good enough seal to begin with . And there is more of a chance of spillage because the coffee can take a relatively straight path out of the hole . The problem will be very pronounced when the tab is flipped to the outside . Then there is the problem with ergonomics . Where does your nose go when your cup is starting to get emptier ? And the scorched lip problem doesn ' t exist on solo traveler type lids . Furthermore the shape is more complicated to most of the traveleresque type lids so the tooling is more expensive .
