I love my Stanley, but it was annoying when it tipped over that the water woud leak everywhere. With this stopper it solved the problem. Super easy to use. I highly recommend.

We've got tons of cups with straws. We use them for coffee and protein shakes, always spilling them if they knock over but not with this.I just wish it came with physical instructions instead of online instructions. Still would recommend
