I purchased my first one of these small cups for my daughter and nephew for Christmas last year, and I have since bought two more for her and one more for him! They were 4 and 7 and are now 5 and 8. They both love them, too. The cups are the perfect size for them! I usually try to buy them on sale since they are a little pricier than what you would normally spend on kids cups, but the quality is worth it. It doesn’t leak even if you flip it completely upside down. Easy for them to carry even if it’s tipped to the side. Keeps ice in the water all day. The straw is not constantly sticking up exposed to germs like Stanley cups. It’s not too difficult for them to raise the straw. And if you have a lefty, just point the straw away from the handle when putting the lid on! The boot stays on really well, but somehow it’s also really easy to take off and put back on when washing. Colors are great and true to images! I wash on top rack and have had no issues with color or design fading, flaking, or anything. It’s really great for elementary kids! I have the middle size for myself and love it as well.
