[This review was collected as part of a promotion.] These were for my two youngest grandkids. They are perfect for a bedtime cup of milk. No leaking!

It has been many years since I have bought sippy cups, but I remember the “drip” issues well. These cups were a last ditch effort after I realized my friend's husband did not bring their sons cup when I watched him recently. These were affordable and I could send one home with him and keep one here for future use. They did not leak at all and he did not struggle with the flow either. Very pleased with my purchase.

I loved these but the lip could twist kinda easy which sometimes it led to spills. only 1 out of the 2 spilled. I had to throw it away. the other one that didn't spill works great!

I like the shape. It's easy for my child to hold with one hand. I like that it's lightweight. It seems that he can open it by himself so I try to watch for that. I really like that it is bite proof because he bites through other silicone straw cups. I should have bought these long ago. They're easy to wash

This cup is great for preventing leaks, and I love how durable and easy it is to clean. It's perfect for my baby to hold and drink from, and the leak-proof design truly lives up to its promise. However, the mouthpiece could use some improvement. The top flares out wider than necessary, and every time my baby takes it out of his mouth, a little drink spills out. It's not a dealbreaker, but it does make a bit of a mess, which is frustrating for both of us. Overall, it's a good cup with excellent leak-proofing, but redesigning the mouthpiece would make it much better. Still, I'd recommend it for parents looking for a sturdy, spill-resistant option.

These bottles needed at least one handle for the children that are learning to drink from a cup or bottle. We are teaching our babies to drink their water from a cup.

Pretty sturdy as far as bite proof, but leaks. The “spill proof” design is one of those s shaped holes and if squeezed or bitten, immediately pours out. Leaks without being squeezed as well. We got these yesterday and by this morning, the blue one leaks when just turning it upside down.

My son leaves his cups laying in the floor and these leak by dripping

It advertises as weak proof and it spilled more than most of the sticky cups I had or have in my main reason was for shopping for sippy cups was for the non-leak proof and I liked their brand with other sippy cups, but not these ones they're more like a dollar or two bread instead of what they're priced for.

False advertisement!! Thiis product States that it is leak proof and states that it's bite proof as well. Wrong! It leaks my child used it the first time and bit a hole right through it! Dont waste your money!!
