First Essentials by NUK Seal Zone Insulated Cup-Like Rim Sippy Cup, 9 oz, 2 Count (Pack of 1)

First off, like other reviewers said, they did not get the design that was listed. I already had some of the boy (blue) cups that I got at target when they were on sale and loved them soo much that I came on here to buy some more but in pink. Based off some of the reviews, the cups that I got at target were the same patterns as they ordered here so I posted a picture of what I got. The girly ones I got here and the boyish ones I got at target but I assume it's the same design since I read another review said whales and bears and that's what I already had. I originally fell in love with two sippy cups. The first cup that I liked was the 360 cups. They were easy to clean and great for learning how to drink out of a cup however, they leaked when dropped or thrown on the ground like any toddler will do or eventually do. That being said I bought the Gerber grip cups and they were the greatest for not leaking, but I just did not like the idea of reverting to a spout but I dealt with it anyways. In hopes of finding the perfect cup, I reached out to the first years insulated cup and although I did like them at first (mostly because of the insulation and less waste of milk) they started leaking after a couple of uses to the point that my 6 newly bought cups that was just over a month old went into the trash. I saw these in the store that stated 18m+ and wanted to try them. I am sure glad that I did because it is truly everything I ever wanted in a sippy cup.Pros:-It's insulated (things like milk and juice last much longer and it stays cool)-It's the most leakproof cup that I have tried (same system as the gerber grips)-It really is like drinking out of a cup. (I have compared both the 360 and this and this just feels like the real thing as the 360 is a bit awkward. The only thing is the child has to be able to understand the drink only comes out of one spot unlike the 360. My child started this cup at 18M and had no problems figuring that out immediately.-The cup is dishwasher safe.-It's one of the few insulated cups that doesn't use a straw. (not sure why this combination is soo hard to find)Cons:-The cup may be a bit difficult to hand wash. The cup is narrow and the rubber seal on the inside has some hard to reach spots. Everything is achievable with bottle brush that will clean nipples too.-It may be difficult to open as another reviewer said. (although my husband pointed out that I am also squeezing the bottle at the same time as turning the lid making it impossible to open.) I found that when I'm not gripping the cup too hard, the top comes off much easier.-The picture is not what you're getting, which is why I posted a picture of what I had.-The seal zone in which you are suppose to tighten to washes off for some reason after a couple of dishwasher uses. It's the only part of the cup that does that. This is not a deal breaker for me as I just tighten it tight and shake before I give it to my child to make sure it is leak sealed.-It can leak if you don't have the seal plug pushed in all the way. This was also not a deal breaker for me. If I shake the cup and it's tight and leaking, this is the 2nd thing I check. Just make sure the plug is pushed down.All in all, I have been using these cups for about 3 months and they are now the only cup I will use and no reason to look for something different.

We went through cups, let me tell ya. My husband picked these up one day and we've been using them ever since. They are insulated so my toddler can have a cool drink all day long. She throws everything and these hold up. The lid has never come off. The part on the inside that makes it leak proof will becomes dislodged after a few good tosses on a hard floor then the drink will leak like crazy. If you keep an eye on it then you're good. I recommend these every time someone asks for a good sippy cup. These are hands down the best. We even paid the premium pink tax for the girly cups, which my daughter absolutely loves, so that tells you how much these are worth it.

Out of what feels like a million dollars worth of sippy cups, I FINALLY found one that actually doesn't leak!!! My kids throw them and drop them a lot and inevitably they all leak...but not these guys! I'm literally throwing out a cabinet full of others that claimed to be leak proof and I will only use these from here on out. To the reviews that said they're hard to open, they can be but I just use one of those rubber jar grips and they come right off. Also, I've found it best to just ignore the arrows to line up the lid, you don't need them. The placement of the top doesn't matter. Just be sure to make sure it's on tight...sometimes it'll feel tight but with an extra little muscle, it will tighten a bit more. Perhaps that is the issue those who say it leaks have. Because trust me...no matter what you do to these babies, they won't spill a drop! It's a small victory for parents everywhere!!!

At one point we had 3 kids 4 and under, meaning my household went through a lot of bottles and sippy cups. It was a realy struggle to find sippy cups I liked; some worked reliably but had 2 part valves to clean out, and the valve needed installed perfectly and if the kid blew into the cup it popped the valve apart. Some leaked. Other's were difficult for little mouths to suck water/milk/juice out of.But these are perfect. The valve is one-piece and easy to remove, clean, and install. The cups are easy for kids to use, both little ones transitioning from bottles and older kids who aren't quite ready for full open-top cups. I have 6 of these, some of which are a few years old and have been used daily for 3 kids and still operate like new.Oh, one other great thing is many other sippy cups and a "nipple" of sorts. All 3 of my kids will chew on any sippy cup with a nub like that and eventually ruin the nub/nipple, doesn't matter if the material is hard plastic or soft silicone. But these don't have that nipple, and my kids don't chew on them. So it's better IMO for their teeth, and makes them last MUCH longer than other sippy cups.

I got this because it looked like stainless steel…. But sadly, the silver is just a sticker/lining on the cup. I think it’s double walled, so it does stay colder than some of my son’s other hard spout sippy cups. It’s definitely not going to insulate drinks as well as stainless steel does, though. I should have known, judging by the price, that it was too good to be true 😅. It’s a great cup though, and the sippy top is totally different than other cups we have. It reminds me of an adult coffee cup lid. Super easy to take apart and clean.So far it’s leak-proof! My son is 2 & no longer teething, so we haven’t had any issues with him chewing on the lid. It might leak if your little one does that. These have a nice flow and aren’t too fast or too slow.I do recommend this, but don’t expect it to be as insulated as other stainless steel cups. **UPDATE: he’s 2.5 now and this is by far his favorite cup!Hope this helps! ☺️

I've had 5 children now and nuk cups are the best around don't leak. Can throw them and still don't leak

These were perfect for my grandson. He really liked the design on the cups. I like the fact that there bite proof.
