“The lids are amazing. They are easy to put on, feel very secure, and they truly don't spill! I completely turned it over and it didn't spill. (It came out the straw hole when I squeezed it a little bit, but that seems fair). The plug part of the sipping section can be difficult to clean, but that's a small annoyance.”
“The best lid for my 16oz pint glass! I love how there is an opening in the middle for a straw AND another opening for beverages like coffee. Even when I accidentally knock over my Silipint, my drink never spills!”
