5.0 out of 5 stars Perfect fit for 40oz Stanley Quenchers
Reviewed in the United States on August 12, 2024
Purchased these spill stopper sets to gift with 40oz Stanley Quenchers and they fit the cups perfectly. I ordered several colors and sets and the colors are also spot on with the Stanley cup colors. If matching is a big thing for you, I highly recommend these. They work flawlessly, like described. No spills or even "explosions". The small case the pieces come in is also very thoughtful and convenient. Really happy with this product and purchase.

Got this stopper kit for my 40 oz lilac Stanley cup and it works perfectly, not a single leak or drip. The color matches exactly, and the pieces were easy to install. Would recommend!

5.0 out of 5 stars Must need for a Stanley !!
Reviewed in the United States on July 19, 2024
I have A cream colored Stanley and this color matches it perfectly !! It’s the perfect size & fit for my Stanley ! Super easy to put on and clean and to make things even better the price is super affordable & it does exactly what it’s supposed to do. My Stanley doesn’t leak at all & that was my biggest ick for Stanley’s, the fact that it would leak but once I saw they had these I was SOLD .

4.0 out of 5 stars Happy with set, but too leakproof for Stanley tumblers
Reviewed in the United States on August 30, 2024
If you install all the pieces of this set on a Stanley 32 oz tumbler, the seals are so tight that you can't drink; it creates an airlock / vacuum and no fluid moves up the straw.

We took off the round seal on the bottom and only use the straw cap and the straw opening cover that goes on top. In our setup, some fluid may leak out from where the pivot cover inserts, because we did not install that leak cover part underneath. Works well enough for our daily needs. It slows the leak process down enough that I can usually set the cup back up before the fluid gets out or with a tiny amount of fluid leaking. Definitely better than not using the set.

I really like the set. I love the color. Straw cap perfect. My husband and I each have one. Colors are great and don't fade. The silicone feels nice and soft to the touch. Fits well with the plasric straw set we bought. Thick but flexible attachment parts that seem like they will last a long time. Enough quantity for spares or multiple cups. Easy to take off and on to clean.

Took off 1 star because:

1. You can't drink from the Stanley tumbler when all the leak proof components are installed.

2. The twist part of the top gets stuck on the leak proof insert when sliding the top to close the sip/straw opening. I have to lift the stanley twist part up a little to get it up and over the edge of the leak proof insert.

I am happy with the purchase even though I think there are opportunities for the vendor to improve the product.

Reviewed in the United States on August 4, 2024
This product does what it says it does and doesn't leak. It was quick and easy to put the peices on and go. At first I had suction issues because it seals so tightly but I just rotated the the round peice that goes on underneath the lid so that the slit in the rubber had a slight gap allowing me to drink easily through the straw. You get a set of two in a little carrying case with instructions. I would purchase them again if I needed to.
