S'well Slide-Open Tumbler Lid, 1 Count (Pack of 1), Clear

do not buy. too expensive for a cheap product

Rubber seals are useless. The lid causes leaks at the seal, so while you're drinking from the mouth piece, it is leaking at the seams right under your chin, leaving a dribble streak on your shirt. Works only if your mouth covers both lid and seam...which is frankly an odd way to drink Terrible design

Me encanto! Solo que si tiene poquito derrame de la tapita negra. Fuera de eso es ideal.

I purchased this to go with the 18 oz tumbler I had purchased, which did not include a lid, which I found surprising. I purchased for use with cold/iced beverages.Maybe it’s just me, but I can’t drink out of this lid without dripping whatever is in the cup all over the place. Still works for travel purposes (not that it’s super-tight, but it’ll work to get it to the car cup holder), but I absolutely have to use a straw to keep from making a mess, which is disappointing.

I have had 2 of these lids and the same thing happened to both of them. The center part of the slider broke and the lid is now less than functional.
