Munchkin Click Lock Insulated Straw Cup 10oz - 2pk (Boy)

These are my son's favorite cups. I originally thought they leaked from the click and lock mechanism, but I found that if I tighten them even further past the "click" then they do not leak there. The only reason I am giving them a 4 is because if turned upside down, they once in a great while leak from the straw part. They are a little work to disassemble and reassemble when washing, but I've gotten really good at it :) You can buy them at Target for cheaper. $4.50 for one or $8.00 for a 2 pack...

Had the Tommee Tippee cups for a bit, got these and switched over. You can see how much liquid is left inside, and they are easy to clean and put together. Milk can splatter a bit if the child lets go of the straw before the liquid is finished, but only the amount between the valve and straw end (1.5" worth), so much better than most!

I got one of these for my son at Walmart. The design and colors were awesome. My son couldn't work the flip top for the straw. It also leaked. I complained to the company and they offered to send a replacement, which I accepted. While waiting for the replacement I ordered this pack of two. The replacement came before they did and guess what! The replacement LEAKED (not to mention they sent a girl cup when I was promised the same design I had bought before). After trying two different cups, I'm giving up and returning these without trying them.We'll use The Insulator straw cup from Playtex. They're so much better and I only wish I'd found them earlier!

My son has drank from these since 13 months old. He LOVES them. I cant get him to drink from any other sippy or straw cups.

See my review of these in a different pattern:  Munchkin Backyardigans Click Lock Insulated Straw Cup 9oz - 2pk (Colors/Styles May Vary) The only additional comment I have about these patterns (we have the dino/robot pack) is that I LOVE that they are fun, kid-friendly designs without being proprietary characters from TV. My baby doesn't watch much TV.

I wish I would have read the reviews before I purchased these. It took them almost two weeks to arrive and I threw them out in about two weeks. They leaked pretty bad after one time washing them. One had water in my 14 month old's bed so that leak didn't work and the other one had his milk for meals which alleyways ended up in the floor and leaking all over that. We bought the Contigo kid water bottles and use them and like them much better.

These cups are terrible. They leak everywhere and do not hold in the liquid with normal use. We used them for milk and washed them after each use and after a month, they smelled like spoiled milk and we had to throw them out. There are much better cups out there - do not waste your money on these.
