we have one of this cups and i use it when we are on the go, it does not leak even after being on the dishwasher several times over a year.

We love these cups they don't spill and you don't have to worry about taking them with you in the car great cups for toddlers

i love all of the Playtex cups including this one. I never have a problem with spills, even if I throw it in my purse upsidedown. Really great cups!

I got this cup for my daughter when she was 12 months hoping to get her off of the spout asap. When she first tried drinking from it she couldn't get the hang of it so we put the cup up for a few months. One night we couldn't find any of her cups so I took out this one and let her try again. It took her about 5 mins to finally get the water out, but once she got it she loved that she had a a big girl cup. It's the only cup she'll use now!

I love this cup. My daughter started using it at 9 months and seemed to pick up that she has to suck to get the liquid out. I haven't had a problem with leakage yet. It's great!

This is probably the best sippy cup I have purchased, and with a 5 year old, a 3 year old and a 1 year old I have purchased quite a few! It keeps the contents cold the longest and it is the only one that after many many uses still does not leak! LOVE this sippy!

my son is 2 and he likes drinking out of it he thinks hes a big boy . I like the idea of not having to use sippy cups with valves. there the best out there

i use these cups for my twins and i love them becuase they are spill proof!

I really appreciate this cup. I use one a day for my son and will use it once my infant is at the stage for this cup. I have never had a problem with leaking.

LOVE IT! My toddler can't spill now and he still feels like a big kid! This cup truely prepared him to use the glass cups we have at home!

My boys absolutely love the Playtex Coolster Tumbler. We no longer use the valves which makes a huge difference. They love the fact that they have "big boy" cups. Plus, they are very durable.
