yeah leak proof

Have tried many different brands and have found that this one is the ONLY one that does not spill/drip. Great product and is all true to description.
Seals well as long as you hear that audible "click" then it is leak proof!!
Will need to buy more..

OUR GO-TO SIPPY CUP!:)

We searched and searched for a sippy cup that our daughter would use. We went from wow to munchkin 360 to tommee tippee and then we found this beauty. A cup that doesn't leak, insulated, has lots of different designs, easy to clean and VERY i repeat VERY DURABLE! If I had a penny for every time these cups have hit the floor I could a gold sippy cup but I wouldn't because these cups are the best.

Re: Playtex Baby Sipsters Spill-Proof Kids Spoutless Cup, Stage 3

We are always looking for a sippy cup that does not leak. We have finally found one that doesn't leak and is spoutless. We really like that it is insulated, doesn't leak, and is preparing our toddler to drink from a regular cup.

Both of my children used these cups. They work great but after awhile they start to leak but the great thing is you can buy replacement valves for them and they work just like new.

These cups were fine for a couple of months and then out of the blue they started to leak... quite disappointed because my son loves them and they are quite expensive.

I went through a lot of these cups they are expensive and I also find that after a while they all tend to start to leak so I would have to try and find ones that didn't. They lasted a while but I think for the price they should never leak.
