HOMDSG Silicone Spill Stopper Set of 3, Compatible with Stanley Cup 40oz/ 30oz, Tumbler Accessories, Including 2 Straw Cover Cap, 2 Square Spill Stopper and 2 Round Leak Stopper

These things are a game changer - make sure you are purchasing the correct set for your style cup. My daughter and I both have the 2.0 version 40oz. We use them for sports and for tournament travel. My daughter had problems as her cup kept getting knocked over by volleyballs and her cup would spill. I had issues as I would place the cups under my seat at tournaments and then continuously knock them over, thus spilling the water. These spill stoppers are a game changer and prevent leaks! Here are my notes from using them as I almost gave up on them. 1. They do seem expensive for what they are but, I get it (shipping and convenience). However, I do like the fact that they include two sets which makes it a good value in my book. 2. They are advertised as BPA free! 3. The sort of rectangular gasket for the straw hole can be a bit hard to get on and almost doesn't seem like it will fit. If you keep working it, it does go on and fit our cups perfectly. One of ours went on super easy, the second one we had to just keep working around the edges with our fingers to get it to go into place. 4. Problems with suction? I had them and was about to give up on this product. However, my daughter said hers was working perfectly which made me investigate a little further. I was having issues with the center gasket round piece. The first time I used it, it fell off into my water. Luckily, it is not big enough to suck up through the straw. After placing it back on suction was awful so I just removed it completely. However, this piece has a small x cut in the center. I found that the rubber was not cut all the way through. I used my finger to push on the area and open it up. After doing this the suction is back to normal and this product is working great! No more spills - my daughter and I are both very pleased!

Works so well! Absolutely worth the price. It's not a Brumate, so the drink will spill if left turned over for a prolonged time. But! It definitely won't spill if you accidentally know it over. Highly recommend!!

These are great! Great fit for my Stanley’s. I buy them for every cup! Highly recommend. The only thing I would note is that if you plan to drink a fizzy drink, be sure to take the center stopper off. Otherwise, these are great for preventing cup leaks.

They work perfectly

I had an issue with my order not being delivered to me as the tracking stated. After I contacted the seller, they offered to reship it, and I received my order much quicker than my initial first order. I believe the problem was the local mail handler. The items were packaged well and works super with my Stanley tumbler. No leaks!!! Great product.

get this settttt omgggg! i’ve had this for over a year and i wash it keep it on my stanley alwaysss. it actually stops my stanley from spilling when it tips over, i drop it, or lay it down unless it’s completely filled up to the brim or above half i would guess which i’ve noticed. i’ve gotten used to all the little pieces and it’s not a real hassle. i like the straw cap the most i make sure it’s always on which makes me feel less nasty when bringing my cup everywhere. i will say that the top part/the cap that goes in the straw has turned yellow and stays yellow after all the washes over the year which idkk maybe that makes sense but it doesn’t look cute. overall it’s a great buy.

Okay it keep your cup leak proof.

Stops the leaks if I drop my Stanley but I’ve noticed that sometimes the water goes up my straw and comes out from the top

No me sirvieron para el Stanley,
