Silicone Spill Stopper for Stanley 30 40 oz Quencher H2.0 Tumbler with Handle Straw Cover Caps for Stanley Water Bottle Leak Stoppers for Stanley Lid Spill Stoppers for Stanley Cup Accessories

Absolutely love these. It is so easy to install and so easy to use. It is an amazing quality that has saved my life so many times the color is absolutely amazing. It is so easy to clean you. Just take everything out wash it and put it all back on. Let me tell you this does not let anything buy. It will not leak highly recommend this for teens that wants Stanley’s but are very clumsy.

This works perfect. The straw cap and part that the straw goes thru into the lid is all you need. The other cap under the lid is not needed. I put it on to try it and I was not able to drink thru the straw because it was so air tight. My Stanley did a flip in my car and not one drop came out. I tried a different brand and it didn’t work cause the parts were too flexible. This brand is sturdy and performs as described!

If you're wondering if they work, they do! I was hesitant and wasn't sure how well they'd work but these all do the job wonderfully. While you can't see in the photos, this Stanley is full of ice water. This makes me feel so much better for my night water as I always knock it off of my nightstand without fail. Now I don't have to worry about soaked carpet in the middle of the night!

Be careful what you order to keep your stsnley 30 oz quencher from leaking. The plastic part that goes to keep the straw tight and also keeps your tumbler from leaking. I ordered these and they were so small they fell right through the straw hole. Im not sure myself which on is correct. The one that came with my cup would pull out with the straw. There is a bigger size thats much bigger kinda hard to get in if you dont have strong hands. But it wont come out when you pull the straw out. It stays in place. The cup will not leak at all. Its a great tumbler. I bought 2 30 oz. They keep cold things cold fot 12 or more hours. Just put pleanty of ice in the cup. I have not tried hot yet. I think if I drank 30 oz of coffee I would bounce off the walls. I have an 8 oz cup for my tea.

The media could not be loaded. Because the product is designed to not spill it cuts off air flow so there is resistance when drinking but it didn’t personally bother me! Absolutely no leaks. Literally turned it upside down and violently shook it off camera as well. It works just as well with my other fun straw topper! Just have to play around with how snug of a topper

Works great, no spilliage .

It appears that the straw sealer and the top rotation sealer fit ok, but my straw must be a smaller size than the Stanley straw and the topper does not fit.

The media could not be loaded. Omg you guys this thing actually worked!! I used OJ in my cup so you can see the liquid better, hug Omgggg now my Stanley is 100% water proof I am so happy!! Only thing is the it was a little challenging to put the mouth piece part on where it has a hole for the straw, but once I got it on this baby works like a miracle, even the straw stopper help with the leak, I’m bout to get me a bunch so I can stock up incasw they stop selling them. A must have for Stanley’s !
