I was excited to use these stoppers on my 30oz Stanley because it always leaks when it is tipped over. I have been on the hunt for something that was small and I didn't have to replace the complete lid to the Stanley because the colors of the lid is coordinated with the body. HOWEVER!!!! I was disappointed that this didn't work like I hoped.The install is easy, but the execution design if flawed. Once the product is on and in place and I try to drink from the straw, the lid dislodges when I draw the drink up the straw. There is a vacuum suction situation created which prevents me from drinking from my Stanley normally. I believe the design is missing some sort of air flow release or something.Sorry but this was a no/pass for me.

I have tried quite a few of these spill stoppers and these ones actually fit and don't slip off into the thermos. I highly recommend these! They fit my Stanley perfect 😁

I mean I’m kinda lazy sometimes, so laying down and sipping from my Stanley has become a usual for me in the evenings. My Stanley drops from the side and this has helped so much! If you’re considering, it’s definitely worth the money to try it out! The only thing I will say is that you have to turn the Stanley straw hole plastic thing to the side because this product won’t fit under it, but that doesn’t bother me much especially for my Stanley not to spill all over me!

I have the Stanley 40 oz. H1.0 and sadly the cap for the middle part of the cover didn't fit. It was wayyy too loose for it to work. Only the part for the straw actually fit. So just be aware of this before buying. Maybe it's made for the 30 oz? Not really sure.

I love that these cover the two areas of concern to make the Stanley spill proof. Many others have two separate covers but this is built in one, which I appreciate since I don't have to worry about one going missing. They do the job well and is definitely spill proof.
