My 7-year olds were fisted 30oz Stanley's with the straw top that came with them...and they spill ALL. THE. TIME. If the mugs weren't $35 I would have tossed them...but instead I found these lids and have maintained my sanity (and my kids can now keep their Stanley's!) Leak proof for sure. I held these upside down and shook them. Brilliant!

I was not able to use it on my standby 30 oz bottle. It did leak.

Not spill proof at all, spills as much as if there was a straw in it. That being said, I got it mainly because we can’t have open bottles in my office and now my cup is allowed bc it has this on it. So if ur in my position and also enjoy the nice hygiene of the straw being closable— they do fit the cup hahah

My daughter asked for these specifically and they do not disappoint! Perfect for taking her Stanley to school or bball practice and not having to worry about spills.

I have a 3 year old and 6 month old who are constantly knocking my cups over. I absolutely needed this for my stanley cup, no more spilling my water everywhere!

These fit my kids Stanleys and didn't leak (as of yet). Although the pink wasn't the same as the cup my daughter was happy. The blue was a perfect match but so far so good.

Fits nicely and for the most part leak proof you have to make sure it’s really down all the way. NOT the color pictured it’s way darker!
