So far so good!

No silicone flaps in the straw waiting to break off into my kid's gulp of water and the straw is wide enough that it doesn't slow my kid down while drinking water - we found that using other cups with thinner straws resulted in our kid being dehydrated by the end of the day. The instructions that came with the cup say that it's dishwasher safe but that it will last longer if you hand wash. They also say not to leave any liquid in the cup for longer than 24 hours - this makes me kind of question the stainless steel an how long the cup will hold up. I have zero intention of hand washing yet another kid thing every day. The cup has been turned on its side and upside down around the house with the lid closed without any leaking so far.

Nice size and color

Great size for small hands. I actually bought this cup for me not for a child and I really like them. I now have four of them. They're really nice to have by your bed won't spill and keeps the water cool for a little while. I would like to see it keep the water cool for longer. I do fill mine up and put them in the refrigerator. My Walmart does not keep them anymore, and I have to order them online

Versatile lid system, cute and functional

It's very lightweight and easy for my 1 year old to hold on her own. I like that you can use swap out the straw lid with the sippy cup lid so it can grow with your child. I have the Thermos Baby Straw Cup in the same color also, that one has the handle so I can interchange them. I haven't had any problems with it spilling. My child drinks water out of it with no problem. She loves holding her “own” water bottle. It fits perfectly in the car seat cup holder and on the side pocket of the diaper bag.
