Re Play Silicone Easy Clean Valve BPA-Free Eco Friendly Heavyweight Recycled No Spill Sippy Cups (Lime Green, Sky Blue, 2pk - 10 oz)

They hold drink for toddler but will leak

Product is solid and functions as advertised.

The cup, itself, is really durable when thrown on the floor. My issues with the cup are primarily in the ability to get liquid out. The valve helps prevent/lessen spills and leaking, but REALLY hinders my child's ability to get much liquid out of it to drink. My LO is 18M and has no issues with other cups, so I'm inclined to believe it's a product issue, not a user error. Aside from that, I do wish it was more see-through, so I can more easily gauge the amount in the cup. Will most likely use it without the top (as an open cup) when LO gets older.

Solid, and do not leak. As long as you check the threads. These have been great for my child who is a chewer. Even after gnawing, they stay leak proof since they don't have a silicone tip. My only complaint is that inside of the lid there are peaks that get dirty and are small enough that they have to be picked out with a toothpick

I bought these sippy cups for my four year-old grandson and he loves them.
