Review: Worth the buy, 10/10 would buy again - Shipping was quick, received a day earlier than expected. One star removed due to a square stopper mouth piece missing, though that was to be expected after reading that in many of the reviews. Very quick and easy to install, simple instructions included but not necessary and came in a nice plastic container to keep the extra parts. The color match is impeccable, you can barely tell they're aftermarket prices. I had about 20oz of water in my Stanley when I installed these, and immediately turned the cup upside down over the sink for 30 seconds, and repeated a few times and found no leakage. Removed star was added back for product doing what it says it should. I handwashed and did not run through the dishwasher and I do not use my Stanly for hot liquids so I cannot answer for temperature retention. I have only just installed so I also cannot answer for durability, but they seem like they will hold up - even the straw cover seems like it will last. Sizing is perfect, the square stopper mouth piece is a little oversized, but that is how it should be and is still easy to install. 10/10 would order again if I purchased another Stanley.
Review: Works great. No leaks. - This works great on my 40oz Stanley, no leaks whatsoever. Instructions are great and it’s really easy to put on. I ordered it in another color for my other Stanley.

This works great on my 40oz Stanley, no leaks whatsoever. Instructions are great and it’s really easy to put on. I ordered it in another color for my other Stanley.

### ⭐⭐⭐⭐⭐ No More leaks
*by B***S on May 12, 2025*

Ever since I got my Stanley I had the problem of it constantly spilling. I can't put it in my backpack because it can't fit in the side and if I put it into the actual backpack it might mess up my work so I had to keep it out of my backpack and it would constantly spill in class or when I would walk with it and it was extremely annoying. I got this to aid with that problem and it works really well. I can completely turn the cup over and not a single drop comes out. The stopper might look too big for the whole but trust me it goes in there and it's pretty snug. My straw stays completely still too. The only thing I don't like about it is that they're isn't any designs available for the straw topper but the good thing is that I can take my existing straw topper and use hot glue to put the design on. Would definitely recommend and would definitely buy again if needed.
