“These are so clever - I love the dual functionality. The only reason I didn't give it a 5 is because the silicone picks up some of the flavor of stronger beverages (coffee) and you have to go through a special process to clean them.”
“I tried the Silipint 16 oz lids as part of the Half Pint Tumbler bundle, and then had to have more of them. As advertised, they work perfectly with the other Silipint cups/glasses I have (16 oz tumbler, 8 oz tumblers, wine tumbler, and Rocks glass). They ALSO have given a new lease on life to several beloved desk mugs whose original tops weren't leakproof or broke over the years.
A note: as a coffee lover who also likes more mildly flavored beverages, the cleaning advice about soaking in baking-soda solution to remove residual flavors is 100% on point. A weekly bath for these tops whether they need it or not, and they're good as new!”
