HOMDSG Silicone Spill Stopper Set of 3, Compatible With Stanley Cup 1.0 40oz/30oz, Tumbler Accessories, Including 2 Straw Cover Cap, 2 Square Spill Stopper and 2 Round Leak Preventer

I’ve purchased these spill stoppers four different times for my Stanley cups because they work so well. Out of all four sets, I’ve only had one issue where the center plug didn’t seem to seal quite right and a little water leaked through the top. I’m not sure if it was the Stanley lid or the spill stopper itself, but it only happened once. Overall, they’ve been a great purchase, and I continue to buy them because they do a great job of reducing spills.

No me sirvieron para el Stanley,

I am loving these silicone spill stoppers. I’ve been using them for about 2 months now and have had so many friends and family members asking me for the exact link and purchasing. I’m that person that has to have a water filled Stanley with me at all times and my favorite happens to be the 40oz tumbler with the handle. Water bottles rarely fit in my cup holders in the car/stroller etc so I find myself taking my Stanley cup everywhere. Surprisingly, these do exactly what they’re suppose to do - stop spills and safely cover the top of your straw. 3 kids running around the house guarantees tipped over tumbler more times than I can count so I love the spill proof pieces and they actually work. I can’t count the number of times I’ve found my cup laying on the floor and no puddles to clean. I initially purchased these for the straw top cover, which is by far the best I’ve tried yet and fits like a glove on all of my Stanley’s, but the whole set has proven its worth. I’ve ordered 3 other brands that claim to fit on Stanley and Yeti straws but they’ve been a fail and actually don’t end up fitting. My only complaint is not having more color options. Don’t get me wrong, the clear is just fine and looks good. I’m just a nerd and would love some fun colors or animal themed ones.

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!

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.
