Great until you need a replacement part.Had these for roughly 8 months now. They’re great but the only reason I can’t give 5 stars is because I need 2 replacement valves and I can’t find any to buy online anywhere. A couple were left in our car with milk in them without realizing and thus grew mold. Despite washing and sanitizing repeatedly, I’ve been unable to adequately remove the mold from the silicone stopper in the valve and of course don’t feel comfortable using it with the bottle. All this despite being able to remove the mold from the hard plastic bottle.
You’d think you’d be able to buy a replacement rather than having to throw away the whole sippy.
NUK, this seems to be a recurring issue among people who buy this type of sippy. Other brands offer replacements. When I need to buy more in the future, I will ONLY buy ones that sell replacement parts.

Spill proofThese cups are actually really enjoyable to hold super easy to clean other than the spot that harbours any liquid other than water. Leak-proof i would say in my top 5 and super durable.

Need replacement spill proof valves!Cups are nice but the plastic piece that attaches to the lid, the spill proof valve, breaks easily. The little silicone piece that prevents water from coming back out will rupture and no longer be fully attached meaning water will come back out. I cannot find any replacement valves anywhere online. When I search all that comes up are replacement nipples for bottles or other types of sippy cups. Apparently Nuk just wants you to buy new bottles after a couple weeks instead of buying new valves.

Best sippy cups ever!These are amazing and don't leak at all! I just wish they had more than 1 "girl" color. I have twin girls and a boy and I'd love to be able to tell whose cup is whose without feeling like I'm giving a girl a boy color.

Nuk Fn Grips Hard Spout Sippy Cups 10ozI need to replace the spouts that fit inside the sippy lid. My grandson has downs syndrome and this is the only cup he will drink out of that won't spill all over him. He's so comfortable with this cup. He won't drink out of any other cup. Eventually the spouts where out and I can't find any anywhere. Since it's a NUK Sippy cup, I feel you should have replacement spouts like I described.

Leak proof and easy to useThese cups are easy for kids to learn on. They have a leak proof insert that can be taken out when they are ready for some spills. The mouth piece has held up pretty well to our kids gnawing. Quick and easy to clean with the removable insert.

Nice grip, but hard for toddler to sipI picked up this sippy cup hoping it would become a replacement for the soft straw sippy cups for my toddler. The only real positive is that it’s easy for her to hold as the shape and size fit her little hands well, making it comfortable and easy for her to use on her own.
However, it requires a surprising amount of force to get any liquid out, which is frustrating. My toddler struggles with it, and I often have to encourage her a lot just to get her to take a sip. I tried it myself and I had to suck on it pretty hard to get anything out. Not sure if this one is defective but I can see why she doesn't want to use it. I had to remove the valve so she'd drink from it but then it spills everywhere. On top of that, it doesn’t come with a lid, which makes it less convenient for travel or even just tossing in a diaper bag. Overall, it’s functional but not ideal. I expected a bit more thought in the design.
