Stanley The Quencher H2.O FlowState(TM) Tumbler Lid - 14 oz Leak-Proof Replacement
OutdoorEnthusiast22 –
Bought this as a replacement lid for my Stanley tumbler. The FlowState technology really works – no leaks even when I toss it in my bag. Build quality feels solid, though it’s just a lid so hard to judge long-term durability. At $6.65, it’s reasonable for what you get. Doesn’t quite match the guise of a premium product, but it does the job well.
