Munchkin® Simple Clean™ Toddler Sippy Cup with Easy Clean Straw, 10 Ounce, 2 Pack, Blue/Green

If you follow the instructions provided this cup is amazing. It’s so easy to clean because the straw opens up. This is the cup that made my 2 year old stop drinking from a bottle!!! Make sure the straw is tightly pushed in and the straw seam is shut tight. Align the arrow pointing up on the straw with the arrow pointing down on the cap. Sometimes the straw would open slightly inside the cup when closed and it will cause no liquid to go up the straw so I make sure to check that if my child doesn’t drink enough. Also make sure the top is very tight pushed on the cup. It may look closed but if there’s a tiny space push more and it will close and be fully leak proof. Virtually unbreakable. Great valve straw. The only cons are that the straw seem can slightly open, the straw doesn’t tuck in great - it pops out - the cons are minute compared to the pros so no stars deducted!

We love these cups. They are easy to clean and the colors are pretty. These straws have better flow rate than the Munchkin Any Angle Weighted Straw Cup, and we use these ones for milk. We have used them for months and they are holding up well. Two catches I'd mention: - For a while my kid would really like to show and unstow the straw on top (at the opening). If he had drank milk with the straw, some milk would stay at the top and this opening / closing action would sprinkle a small amount of milk onto my face / kid's face / carseat. - You need to be careful in sealing up the straw properly when assembling it and also push the straw into the lid far enough (so the bottom of the straw doesn't touch the bottom of the cup). If not, the straw would split sometimes, and it is very hard to detect that other than seeing the kid reject the drink. Since the cup is not transparent, I would need to remove the lid sometimes to inspect the straw to see if it needs a fix. Despite the two catches, these are still our current favorites for giving milk, so 5 stars :)

These are my favorite spill proof cups that fit in the car seat cup holders. The only con I have is that my toddler chews on the straw lid and causes the silicone to eventually tear. I wish munchkin sold replacement lids. I surprisingly love the split straws. Definitely easy to clean and stays together well as long as you line up the arrows. I didn't expect to love the straws but I do.

so far my fav sippy cup for my toddler. easy to use, doesn't have a dozen little pieces, and it's no problem washing. can just go in the dishwasher! doesn't leak at all. i wish they had more girl colors though!

These are pretty good. They don’t leak when tilted upside down. Very easy to clean. My 12 month old immediately loved them. However, they’re not screw top, so securing the lid so it’s leak-proof is an art. Again because they’re not screw top, if your kid likes to throw bottles down from their high chair or other heights, there’s a chance the lid pops off and spills everywhere.

I really like this straw cup because it’s relatively easier to clean compare to other straw cups. I just split open the straw to clean and use a pipe cleaner for the part of the straw that doesn’t split open. The drinking part on the lid I also need to use pipe cleaner but it’s easy since it’s not narrow. My 11 month likes drinking from this the most and can hold it even with one hand. I filled it with water and dropped it on the floor a couple times from high chair level and it did not spill! It’s not completely leak proof baby can fling milk that’s still on the tip when it’s throw or smacked (hard to get around this for most straw cups). I do wish the lid screws on instead of pushed on to close to make sure the lid stays put. I didn’t notice initially, but there are tiny arrows you need to line up the lid and bottle as well as arrows on the straw. Otherwise I am happy with this affordable purchase!

These are the only sippy cups my grand-daughter will drink out of, they are light weight and leak proof, you have to have the lid on just right and lined up. I like that the straws open for easy cleaning and they hold up to 10 ounces. There's a round tab on top that holds the straw down.

I really wanted to like these cups. The idea of the straw opening lengthwise for easy cleaning sounded perfect. But in actual use, it’s been more frustrating than helpful. The biggest issue is that the straw opens on its own. When that happens, liquid won’t come through, so I constantly have to check and adjust the straw before giving the cup to my toddler. It defeats the purpose of a “simple” cup when I have to troubleshoot it every time. Cleaning is another problem. Even though the straw is designed to open, it still traps residue. The first time I put milk in it, there was still milk left inside the color part of the straw even after using a straw brush. Because of that, I only feel comfortable using these cups for anything else but water. And finally, they do spill more than I expected for a toddler cup. Overall, the concept is great, but the design doesn’t work well in real life. Easy to clean in theory, but not reliable enough for everyday use. I wouldn’t buy them again.
