BUILT isn’t a good company
"I bought these in the hopes of working with the deceptive, not-as-advertised 30 oz tumbler replacement lids that have mysteriously removed the straw notch. They did not work with them either. Also, they are too short for 30 oz tumblers. I beg you to not buy from BUILT. Learn from my mistakes and don’t give them any of your hard earned money."
