Ya win some ya lose some ...they certainly do leak.. But i couldnt get my daughter to take a sippy cup with a hard top... Its a great transitional cup even though it leaks.

Leak They are a great price but they leak and the nipple pushes in a lot.

Just purchased three of these for my nine month. They are easy for him to grip however the tops don't secure very well. Also whatever you decide to put in the cup leaks out extremely easy.

Great transitional cup for toddler only issue is that cup leaks from top

These cups are absolutely amazing! The only downside I have noticed is that the seal around the top seems to wear out after so much use, but for the price it is well worth it!

My daughter loves this. Its a very good and one. She hates all the others

This is a great sippy cup with very little spillage. This is one our family has used with all the kids in the family so far. ..

Wasn't a fan of the nuby sippy cups, found they always leaked from the nipple.

When bottle breaking these were a life saver. Especially the ones with the straw design. Thank you so much!

This is the only sippy cup that my son will use. He loves it!

These are AWESOME!!! Haven't had any issues with them so far!

I had a very hard time getting my youngest to change from a bottle to a sippy this was the only sippy she would use.

Great for the toddlers! Fairly easy to clean the nipple. Doesn't spill unless the nipple is bitten out of shape.

After a few uses, these always leak. I was not happy with the quality at all.

My daughter really liked these cups. I thought they were great, they don't leak. I thought they were a bit hard to wash.
