great transition to regular straw cup
I didn't do that much research, I just noticed 1 day at our kid's daycare pickup that at least 8 other kids in the class had this exact cup, so I assumed this was the best out of others. it's pricey, so I bought just 1 cup at first at daycare, and still used our philips avent at home. it is slightly more annoying to clean than a standard bottle, but it's as advertised - spill proof and very durable. we use it for both cold and warmed up whole milk. it's not super insulating though if you care about temperature retention. we bought the 10oz because our kid sometimes drinks more than just 6oz, it's a good size - not that large. the rotating handles are a genius design choice because sometimes your kid is side lying and can still drink from the bottle which is nice. do note that these type of snap top lid means the lid will hit their face when theyre drinking lying down, but it's totally fine at daycare where they only drink during meal times. plus I didn't want to deal with missing or mismatched lids at a daycare situation. we did finally buy a second grosmimi for at home use, and did not get the snap top lid version for that (which is cheaper). FWIW the snap top lid is very high quality and well designed. we did have an issue in the beginning where our toddler would be gnawing on the straw mouthpiece and had to buy the replacement parts only within 2 months. but after that he moved on from that phase, so don't plan to replace for a bit longer.

Best cup in the world - only cup baby uses - worth the $$
Literally this cup is so good this is the second one I’ve purchased but in this larger size. My baby hates all other sippy cups but immediately loved using this one and drinks the amount of water she needs thanks to this cup. So easy to clean for us parents, durable (she throws is all day long), never has leaked, and is so cute! I’m eyeing the insulated one for summer time.

Best leak proof kids cups on the market!!
We are a Grosmimi cup family through and through!! They are the best kids cups. They don’t break when your kids thrown them, they are dishwasher safe and the quality is fantastic. The are also the absolute best leak proof cup we have tried!! Worth the price! Love that this one has the flip lid for older toddlers. The button is easy enough for them to push open. And the handles are also so nice for kids to hold the cup with both hands. I recommend these cups to every parent I know!

Great
Great sippy but handle is not steady, it is loose and moves around which makes it less convenient for me and my child. The straw really reach the bottom though which is nice

Totally worth it!
This is hands down the best sippy cup for your toddler! My son really love this - he started using this at 18 months and we never looked back. He's used to use the Dr Brown sippy cups but those are really hard to sip up. And it's not really good for mouth development. So we switched to this Korean brand and it's a life-changing product. Use this everyday twice a day morning and night for his milk and water. He has no trouble sipping this and no frustrations. Do you think your son is frustrated and drinking milk it might be the type of straw that is used on the product. Very easy to clean and it is leak proof just make sure that you seal it correctly. Use the baby breeza formula maker. It might not detect the bottle itself however you just need to put the handles on the bottle and it will work. It is however on the more expensive side for baby bottles. But it is totally worth it when your child have no frustration drinking his milk. The weight actually lighter than Dr Brown sippy bottles. Very portable and very easy to clean. Also very durable since my toddler likes to throw things around and he specifically likes to throw his bottles around. It did not crack at all. We did got another set so we have a total of four just for circulation of bottles. No hesitation to get this again if we need to. Get it when it's on sale totally worth it.

Be sure you want to only like these before buying.
Okay, after over a year of use it’s time for me to finally write a review. The chokehold these stage 2 straw cups have on our family is insane. I have tested SO many other cups that claim to be leak proof because I have a cup dropper who drinks whole milk. No matter where he is, when he decides he’s done drinking he’s throwing his cup down right then and there. This is the ONLY CUP that does not have be deep cleaning massive piles of milk off beds, rugs, the backseat of my car, and my couch. Can he fling droplets the milk that’s left in the straw around the car? Yes. Does he, also yes but that is nothing compared to the messes other cups make. It’s also important I mention these are so much easier it is to clean versus the other cups that claim to be leakproof and have 100 parts. I soak the straw parts in sensitive soap and vinegar when they get a smell and replace them every 1-2 months. We keep about three cups in rotation at a time. The only downside is they are pricey. So before you buy them and fall in love with them remember you will probably spend over $400 a year on baby/toddler cups.

Not as spill proof as I thought
As much as I wanted to love this cup, i wasn’t impressed as many others reviewed. It is easy to hold and clean. I say it’s durable, sometimes it seems like lid would untighten and the cup would leak.
