Great Replacement – Truly Leak-Proof! These lids are a perfect fit and genuinely leak-proof, which I love! They’ve made using my tumbler even more convenient. The only small issue is that the straw becomes difficult to use when the lid is screwed on very tightly. To work around it, I just loosen the lid slightly, and then the straw works perfectly. Overall, it’s a great buy and does exactly what it promises! Read more
