These straw cups work great. Fairly easy to take apart to clean & once you understand the cup it's easy to put back together. However, i find that liquid sometimes sits inside the upper section of the straw which has caused a mess when dropped or when trying to close some of the drink with ooze out. But they clean well in the dishwasher & being insulated they help to keep the drink cool longer. I have had these cups for almost 2 years & so far they are all still working without problems
This was fun at first. My daughter eventually started to bite through the straw so that was concerning. It also would spill if tipped over. The flip straw would squirt the liquid whenever it was opened and would go anywhere.
I love the "lock" feature. It stays shut even when it's thrown or when my curious 2 year old is trying to open it. The straw is durable even with chewing and of course the designs on the outside like Elmo make it her favorite cup
These are my daughter's favorite cups! It did take her awhile to figure out how to drink out it but they're great for evading messes. It can leak a little bit if you don't close the straw back up but nothing too crazy.
