Amazing ergonomically designed product loved by everyone in my family.
Ingenious design as the floating flexible straw always gravitates to the bottom of the bottle so you don't have to raise the entire bottle up for the baby to feed.

Great for transitioning babies
Our little one loves using this bottle to drink water. It’s extremely easy to use and very durable considering our baby likes to throw things. It’s not that easy to clean and is not 100% leak proof. Many times I’ve had to clean up water messes, but they’re not as bad as some of the other bottles. I think it’s still a well designed bottle and a good value for the money. Just as long as your little one is inclined to make use of it.

Great Quality
Was really excited to get this as we are weaning our baby off of bottles. The quality of the cup is great but my baby didn't like it. It is a cool cup that works as advertised but unfortunately it is not a direct replacement for a bottle.

Baby loves this cup
My breastfed baby refuses every bottle but loves this silly. It doesn’t leak, easy to clean, and well worth the price.

This is our very first attempt with this cup.
The media could not be loaded. Usually when weaning it will take them some time to get use to a cup because (at least for my son) he absolutely loves his bottle. So I expect him to not take to the cup immediately. It will probably take a few days before I know if this is a winner or not. But what I can say about this cup is that when I bought it I felt extremely hopeful. I’ve bought every cup that Walmart has, and he absolutely will not drink out of any of them. He loves his bottle like I love my nicotine gum 🤣. Anyways, In the video I attached to this review, it’s me giving him the cup immediately after I opened it washed it. He doesn’t appear to be happy with it in the video but what I noticed is that he actually took some drinks from it. (Unfortunately, I think he’s in the habit of immediately getting mad and throwing the sippy cups) that’s probably why he decided to hand it back to me at that point. I’m optimistic though, because he did end up wanting it back and actually drinking out of it. Which is rare for him. Usually it’s a little drink then he gets mad, throws the cup and throws a fit. This whole bottle weaning thing is not for the weak. All I can say is stick to it and follow through. It is getting better for us, and we haven’t even found a sippy cup he will drink his milk out of yet (he’ll drink water and juice during the day out of whatever cup) but i am on the hunt for something I can put his milk in and he can drink before he takes his nap and goes to bed. (No milk after he goes to bed because it’s bad for his teeth and that’s the hardest part and really there isn’t anything we can do except push though it and hope that he will eventually just get use to the change) but I’m hoping this cup will allow him to wind down and relax and enjoy his milk before I lay him down.Oh yeah, one thing I did notice that Has been a big issue with a lot of the other cups I’ve bought, Is that The part he drinks from Gets sucked in When he’s chugging it and it takes a minute for the air to get back in the cup and it to inflate back up again. Like I said that’s been a big issue with the other we’ve had but the good thing is, it doesn’t prevent him from drinking out of it. So hopefully it won’t be an issue with this just to see.Also, it doesn’t leak as much as pretty much every other sippy cup I’ve gotten. Although, this is the first day so we’ll see as time goes by. Unfortunately it’s not 100% leak proof because when he throws it, it does splash a tiny bit of milk out of it. I think whatever’s Stuck in the straw from his last drink. But I did shake the cup upside down when I had it in the sink and I shook it a lot, and it didn’t leak like that. So that’s a step in the right direction. I have high hopes for this cup.
