Munchkin® Click Lock™ Bite Proof Sippy Cup, 9 Ounce,2 Count (Pack of 1), Plastic, Blue/Green

I bought these for my grandbabies and they use them all the time. I even have my son ordering them. There easy for them to grip and hold. Easy to use, sturdy and dishwasher safe. And they don't leak and very easy to hand clean also.

Got this for my 13 month old. We originally got the type of sippy cups with the straws and the weight in the bottom but I found those very annoying to clean on the day to day. These however, so far, are about as leak proof as they get. I was nervous about it not being very leak proof because the photos don't really show HOW it is leak proof. My son has to bite down on the mouth piece and then drink, so it seals pretty well when he is not drinking. There is a slight amount that sometimes spills out because there is some that collects in the mouth piece inbetween sips, but its no more than a couple of drops.Its also super easy to clean, which is my favorite part. We can hand wash easily and quickly, or just throw it in the dishwasher. The mouth piece seems super durable so I feel it will last a LONG time. I plan to buy many more.

**UPDATE**Been well over a month & still holding up amazingly!! We have 10 total now. No more bottle use now only these cups. Babies sleeping through the night thanks to these! My son’s have chewed the living daylights out of the spouts yet they show no evidence of wear & tare except for 1 which does have an occasional slow drop here or there but that’s it. Told all Mommy friends about them. Get them! You won’t regret it!LOVE THESE! Really struggled with which to buy & bought several different cups at one time. Hunting for BITE proof cups that didn’t leak & didn’t have a SUPER hard spout. These are the winner! All others I’m returning. Finally found the perfect cup!! Truly are 100% leak proof, I was really surprised, but it’s true. My kids throw the cups every where, dump upside down, bang them on furniture even while upside down & constantly leave their cups laying around in their sides yet still no leaks! The spout sticks up enough but not too much.Perfect size & shape for little hands (especially if trying to trick bottle stubborn babies into these are new bottles) I was worried after reading reviews that my kids might not be able to figure out the whole BITE DOWN AND SUCK at the same time to remove the liquid. They had no trouble at all! After a few minutes & a few tries they figured it out no problems. Both kids immediately took to this cup! Love the click so I know it’s closed. Super easy to clean. 2 weeks in & my toddlers knaw/chew/bite on the spouts constantly yet still not leaks, no rips/tares/splitting/totally intact! Same condition as when we first bought them! The spouts are a soft type but reinforced so my picky babies take these unlike the hard spout cups they hate. This also is an actual sippy cup vs a glorified bottle like the Nuks we were on. 18 month old (was EBF until 15months then weaned) & a 3 1/2 year old. Trying to get both off bottles. We use to use the Nuk sippy cups but both kids kept biting/chewing holes in the nipples where the opening would end up a gigantic gaping hole as well as swallowing some of the silicone. We’re replacing nipples weekly w/Nuks! We needed something else that was less like glorified bottles. 18month old was super picky & wouldn’t take hard spout sippy cups & 3.5yr old would use any cup except at bed time & refused any type except the Nuk silicone soft nipple cups. We’ve now got both kids transferred to these only! They LOVE them & so do I! I originally ordered only 1 pack so each baby had 1. Reordered FOUR more of these double packs & cant wait to get them tomorrow! Btw, shipping was excellent w/free next day ship thx to Prime, & packaging was great. Put together, all parts there so nothing missing, and packaged nicely not thrown in haphazardly. SO pleased! Can’t say enough great things about these! Would recommend & am going to recommend to all my mommy friends! And I’m a paying customer, not a promotional review, so my review is honest. I rely heavily on reviews for my online purchases so i hope this helps! You won’t regret it!

I guess these really differ depending on the kid you use them for, but I've used these for both of my children. Currently using them for my one-year-old son, and used to use them when my daughter was like a year and a half. They don't just claim to be by resistant, they claim to be bite proof! And they were for a while with my daughter until she was able to bite a hole in the clear plastic right below the colored part of the sippy nipple. Then again she had a full set of teeth pretty much at like a year. So I am knocking these 1 star because they did claim to be bite proof and not bite resistant and she was still able to bite through them. I ordered another set for my son now that he's turned one and so far they are going good. He does chew on them but he hasn't been able to bite through them yet. I see these lasting for quite a while so overall I'm pretty satisfied. Out of all the trainer kind of sippy cups I do recommend these the most because they have been the ones that stand up to the most biting. I also like the shape that makes them easy for small children to hold.

These sippy cups are exceptional in terms of durability and spill resistance. Additionally, the packaging is entirely recyclable, which is commendable. My son appreciates the vibrant colors and the ergonomic grip.

Bought for grandbabies. They are easy to use and easy for them to hold. The cups are not spill proof tho. Bright colors and the perfect size

These are durable, but they leak a bunch. If my son doesn’t drink it just right (he is just transitioning to a sippy cup), it is all over his chin and clothing.

I like them for my grandbaby
