HOMDSG Spill Stopper Set for Stanley Cup 2.0 40 oz & 30 oz

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.

Does its job! The trapezoid insert for the mouth hole lOOKs like it won’t fit or is too big at first but you just have to finesse the rubber in and then it fits great, with the other circle cap and the plug, zero spill!!

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.

This really does make your Stanley cup spill-tight! I still had some issues with water overflowing over the straw, but that really only happened when I overfilled my cup. I definitely wouldn't throw my Stanley around as casually as I would a water bottle with a lid, but this does reassure me that I can put the cup upright in my bag and the chance of spilling on my stuff is significantly less! I already had a cute straw cap that I preferred to use, and the other pieces work great with that cap!

Definitely purchase. It's only a few bucks but definitely worth it, especially if you have a tumbler. I just got it for the straw cap, but the other pieces made my cup spill proof. I recommend

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

This is a great product! It really works! It's almost perfect. The only water that comes out is if you turn it upside down completely, a very slow leak comes out of the spot where the straw hole is. Otherwise no water anywhere. Way better than it was. Almost perfect! Definitely buy is your wondering!
