These are very great quality every day kids to-go cup ! They are sealed tight and spill proof as well as being very easy to wash at the end of the day. The only critique my son gave is that it doesn't hold enough liquid. If there is a larger version it would be perfect!

My nearly two year old has been using this cup. And while it’s for the most part easy to use (the clasp to release the lid can be hard for younger kids) the bottle is also not as leakproof as the description says (my son loves to turn this cup upside down and water leaks through the straw).

Son liked it because he can see through to know how much water is in it, but thought the placement of the handle in the back made it uncomfortable to carry. It holds just enough for an afternoon outing. It fits nicely in car cup holders. We like that it locks, so when grabbing by the handle or sitting on an uneven surface, it doesn't accidentally pop open and spill. Would recommend.
