made my stanley almost completely leak proof. before i was constantly worrying about it tipping over and soaking everything, now i use my stanley worry free. its a bit difficult to fit into the lid, but it has to be tight so its waterproof.

My daughter is 15 and takes her Stanley EVERYWHERE! It was always spilling as she's active and constantly on the go. I purchase these for her and it eliminated the leaks ! the only way it will spill now is thru the straw. A lot less accidents since and super easy to put in ! Great price as it comes with a few replacements for different types of cups ! Works amazing, looks flush, and suctions onto the straw to prevent the leaks ! Even worked with the replacement straws i bought her! Great product we're happy!

It says that it could fit a 30oz StanleyBut it did not fit my Stanley that was exactly 30oz but otherwise I gave it to my sister because it fit her Stanley and also it didn’t fit on her Stanley either. I don’t know what kind of Stanley fits on but it doesn’t fit on my moms Stanley, my Stanley or any Stanley, so I am rating this product three star because I really don’t like it I like how it’s plain one star I like how it at least bit of the straw thingy fit, but I didn’t like a lot of other things so that’s it

My niece wanted a Stanley but I was worried it would leak everywhere and didn't want my sister to kill me lol. I got these to help and they did.

Works really well! Easy to clean, take on and off, and has a low profile design. It’s durable, easy to use, and suctions well. Excellent value for the money!

Absolutely no leaks, Stanley makes a great product but it leaks, water spilled all over my car seat without this product. Don’t buy the tumbler without this product.

I LOVE having my Stanley. The only issue is the leaking! I have kids and animals so it’s always getting knocked over and spills everywhere. If I’m juggling multiple bags and my Stanley it gets tilted and immediately spills all over me. It’s so irritating. It got to the point where I almost gave up using it. I searched for a possible solution and came across this silicone stopper. I definitely had my doubts that this would fix the spilling issue. When it came in the mail I immediately put it on and tested it out by turning it upside down over the sink. When I say nothing came out, I mean NOTHING came out. It’s been knocked over several times in the past few days and still no leaking. I am so relieved to have found this. It also helps that it’s clear so there’s no noticeable insert in the straw hole. The only thing I will say is that when you go to pull out the straw the stopper tends to come out with it. Honestly though, I just take it as a demonstration of how tight the seal around the straw really is.
