Was apprehensive at first about these, but they truly work. When they are installed, the cup can be turned upside down and will not leak at all. This is a great investment if you have small kids that would spill a lot.

Works perfectly, a little small and can lose when washing, but does exactly what it says!

Reviewed in the United States on September 27, 2023
I LOVE having my Stanley. The only issue is the leaking! I have kids and animals so it’s always getting knocked over and spills everywhere. If I’m juggling multiple bags and my Stanley it gets tilted and immediately spills all over me. It’s so irritating. It got to the point where I almost gave up using it. I searched for a possible solution and came across this silicone stopper. I definitely had my doubts that this would fix the spilling issue. When it came in the mail I immediately put it on and tested it out by turning it upside down over the sink. When I say nothing came out, I mean NOTHING came out. It’s been knocked over several times in the past few days and still no leaking. I am so relieved to have found this. It also helps that it’s clear so there’s no noticeable insert in the straw hole. The only thing I will say is that when you go to pull out the straw the stopper tends to come out with it. Honestly though, I just take it as a demonstration of how tight the seal around the straw really is.

4.0 out of 5 stars Finally making the Stanley not leak .... a product we all knew we needed
Reviewed in the United States on March 7, 2024
Thank god someone finally made these because lets be real, we arnt going to give up the bragging rights of owning a Stanley. The instructions were not help but it was pretty self explanatory how to put it together. Tested pretty well shaking up and down and had no spills even from the straw. My only complaint is that it creates a vacuum effect while drinking making it kind of difficult but all you have to do is let go and drink again, I guess an annoying price for the bragging rights.

I have been using this for three months now and my Stanley cup has never leaked. The suction power is not affected by the rubber pieces whatsoever.

Reviewed in the United States on March 29, 2024
It says that it could fit a 30oz Stanley
But it did not fit my Stanley that was exactly 30oz but otherwise I gave it to my sister because it fit her Stanley and also it didn’t fit on her Stanley either. I don’t know what kind of Stanley fits on but it doesn’t fit on my moms Stanley, my Stanley or any Stanley, so I am rating this product three star because I really don’t like it I like how it’s plain one star I like how it at least bit of the straw thingy fit, but I didn’t like a lot of other things so that’s it

Reviewed in the United States on August 30, 2023
We got these stoppers for our Stanley's before we left on a three week trip to Germany, hoping to avoid spills throughout our trip.
They suck! First time my husband knocked his Stanley over on the flight to Germany everything came dribbling out all over the floor.
It was game on from there! Knocked over a full Stanley of water on a very very very old wooden pew in the Gothic Cathedral in Cologne Germany. No help there!! Frantically trying to mop up spilled water before we permenantly gave water damage to a piece of history.
Can't tell you how many accidental dousings I suffered on all the train rides.
These things are pathetic. Don't bother!!!!
