Your Stanley WILL drink differently!
Stanley Cup lids are made the way the are for a reason. However, if you're a diehard Stanley user, leakage will eventually be a problem. These additions DO work. That being said, you will notice a difference in how drinking from your emotional support cup changes with these in place.The seal around the straw is TIGHT! Leak-proof tight. The cap that goes over the....middle part(?) creates a seal as well. This creates a vacuum when your sucking on the straw. You may hear a whine/whistle while drinking. It's like the sound a kids sippy cup makes. (Notice how they are leakproof also?) The most noticeable thing is when you stop sipping from your straw. That vacuum releases and you'll hear and feel the air suck into the cup as soon as you take your mouth away from the straw. All of the is NORMAL! (Science is cool!)I like the addition of these products to my Stanley. As long as you have ANY leak proof straw topper on, they make your cup 100% leak free!

Very helpful
These are very helpful. I do wash them at the end of every use and put them back on my cup in the morning & they work just fine.

Worked for my 30oz Stanley
Stopped my stanley from leaking. However the straw cover could have been a tighter. Liquid can still leak out as it doesn't fit snug but better than it was to start with.

Does NOT fit the 40ox Stanley lid as it's TOO THICK
I bought these for a gift, too late to return now. But they do NOT FIT the Stanley 40 oz lids. They are way too thick, and you can't get the top to turn. Can't use them and too late to return.

Works just as described!
Perfect to add to any tumbler to prevent spills!

The gotcha
Oh it definitely works to make your cup leak proof, but what they don’t tell you is you cannot drink out of it without having to suck very hard. I found myself unscrewing my whole dead just to be able to get more than just a tiny bit out at a time.

Actually works!
The media could not be loaded. I’ve tested this several times with the cup being different levels of full and never a drop.
