David ★★★★★ Sep 11, 2026

My toddler chews on the dust cover constantly and it eventually cracked, so this two-piece kit got the cap working like new again. The air vent gasket fits snug and stopped the slow drip that was soaking my bag.

Emma Y. ★★★★★ Sep 11, 2026

Lost the original air vent gasket somewhere in the dishwasher and this kit had me back in business in two minutes. The new gasket seals tight, no more drips in the diaper bag.

After a year of daily use, that little dust cover finally cracked, and this kit got our cup back in rotation for a few bucks instead of buying a whole new cap. The replacement gasket seats snugly too, no leaks in the lunchbox so far.
