Review: Great cup - This training cup is perfect for helping toddlers move from a sippy cup to a regular cup. The free-flow design lets them learn how to control the pour, and the size is just right for little hands. It’s lightweight, easy to clean, and I love that it’s BPA-free and dishwasher safe. The lemon color is bright and fun, and my toddler took to it right away. A great next step in building confident, independent drinking habits!
Review: Great for learning to drink out of cup - Love this brand and this cup has been great practicing drinking from an open cup without making a ginormous mess. I like that the top is clear so you can see the water when you tilt it in your mouth. There's no spill protection so the water is free flowing, which we like for practice much better than the 360 type cups, but you do need to be quick when your toddler tips the cup upside down. Helpful that the opening is also clear so little one knows where to put there mouth to drink. Has been through the dishwasher quite a few times with no issues. Same base as the no spill straw cups (which we love!) so you can swap the tops around which is convenient. The logo eventually scratches off with lots of use. Definitely recommend!

### ⭐⭐⭐⭐ Spillage
*by L***N on October 16, 2023*

It’s a great cup and the lid is perfect, but it does still let toddlers tip it upside and spill out. I was hoping to a i’d that, but it is an open hole. Easy for kids to use and pretty easy to clean.
