I like these cups..the price is good also...they do leak but u get what u pay for!

These are great as long as you don't just throw them in the diaper bags. If you generally keep them right side up they are great. My favorite are the ones with the straws

I started using it when my son was 6mnths.He never liked bottles since he's exclusively BF.We bought juust to give it a try.He liked it and figured how to hold it and all quickly.I would only give him water in it.Once he was about 10 mnths he figured how to tip it upside down and press the tip to make it spill.So we now stopped using it.But it works well for the price.

I like this product . Easy for your child to hold. They are decently priced and have found them to be spill proof.

A great transitional cup. Leaks like every other sippy does. I'm used to it.

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

Love this product. We have purchased one with each grandchild. No spills and no matter how far the kids tip them up, they don't get too much at a time. They are easy for the kids to hold. and they wash up nicely in the dishwasher. Great product for a great price!

LOVE THIS BRAND! LOVE THIS PRODUCT! I have never had any trouble with leakage with any Nuby product! I love these cups. They are very inexpensive too, which is even nicer. I love Nuby's customer service! They are the nicest company I have ever experienced. I have won several free online from them just by liking them on facebook. HIGHLY RECOMMEND

I have lots of these cups and my 16month old loves them. She had a hard time switching from bottle to cup and the nuby cups are the only ones she would take. They do leak a bit if you turn them upside down and shake them. But I know through experience with my first daughter who is now 4, that no matter what they advertise there is not a sippy cup out there that does not leak a little. I like these because they are inexpensive and if my daughter throws one out of the stroller and looses it or the nipple doesn't work over time they are cheap to replace. I give these a 5star!!!!

I love them..mine do not leak,and i love that they do not have as many pieces as the other sippy cups

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. ..

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!

I have used these cups with both of my children. I personally have never had issues with excessive or obnoxious amounts of leaking or nipples getting sucked in. In fact, these are the only sippy cups my daughter would drink from instead of use as a chew toy-and believe me, I bought several to try out, and from more expensive, affluent brands. Nuby is phenomenal at pleasing their customers, and would seriously suggest that those who have complaints about leaks (I think minor ones can be expected) and durability to consult their customer service, and to get an even quicker response, their Facebook page. They are on top of their game when it comes to trying to maintain a positive reputation.
