Silicone Spill Stopper Set Compatible with Stanley Cup 2.0 30oz & 40oz with Straw Cover (Set of 2, Pink Dusk)

I bought these because I was sick and tired of knocking my Stanley over and it spilling everywhere. After putting these on I could honestly throw it across the room and it wouldn’t spill a drop. The color matches perfect and it was all fairly easy to put on as well. I will definitely purchase again and recommend to anyone that wants a leakproof Stanley!

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.

I recieved this today and immediately put it on my cup, and turned it upside down. It 100% works! No leaks anywhere. I highly recommend this! Also, the color matched my cup perfectly. I couldn't be happier.

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.

My granddaughter found these! They fit perfectly on the straws that fit in her Stanley that she takes to school every day. These are 100% spill proof in her backpack. Worth every penny!

I got a stanley as a gift and love it stays cold forever and I feel makes me drink more water, but it spills easily. This little set works wonders!! I do however remove the small inner cap cover when I'm finally at my destination in order to drink easier, since w that cap on, it's hard to get much water from the straw.

This works really well for a month or two until recently the straw cap seem to get loose after a month or two now it keep popping out from the straw

My daughter wanted to take a Stanley to school and these help so much from it leaking/spilling. Highly recommend!

Ça fonctionne bien. Il est très étanche.Je vous le recommande.

This item is great. It keeps the water bottle from leaking.

No se ajusta al tamaño del termo para el que supuestamente fue disrñado

Really works to make my Stanley tumbler leak proof and you get a lot of sets for a great price

Great product! Completely leak proof! Just make sure your cup is tightened!
