Definitely leaks, bottom half of the straw falls out and floats around in the water- who knows how long my sons going without water before I notice or he bring it too me. Waste of money, don’t buy.

We had this bottle for my older child and it was great so I bought another for my 22 month old and have realised it’s actually really difficult to use. He has to bite the straw while sucking; he just can’t understsnd no matter how much I demonstrate. i’ve Given it a 2 star rating as it’s great if your child can figure it out, but probably not great for the 12 month + age group it is marketed to.

This cup was great and Didn't leak for the first couple of days now it leaks everywhere. Also the straw keeps popping off the little knob part in the inside, so I'm constantly having to take the lid off and put back together. Super disappointed and will never buy again.

The straw falls out and floats in the bottle. Child gets NO fluid every time and straw needs to plug into a slot in the lid. USELESS waste of money. Useless and extra straws needed. Useless.

One can't draw any water from it unless the straw is squeezed... how annoying. The child got very frustrated and discarded it. Size and shape are fine, but unless the child bites the straw, no liquid will come out.... good design? I think not.....after all once the straw is folded in place it doesn't leak.

We were so excited to finally find a cup our daughter would drink from. Other straw cups were too hard for her - we think. Anyway was really disappointed that the lid comes off the bottle way too easily when dropped off the high chair onto the ground. Got so sick of mopping up puddles of water that this one is going in the bin!

Bought two of these bottles, both of them began leaking only a few days after use, leaked from between the cup and the screw on lid. When dropped, the lids came straight off spilling milk or water everywhere. Both bottles were thrown out within a week, wouldn't buy again or recommend.

I couldn't fault it if it didn't leak! It literally leaks no matter how careful you screw the top on. So you must be careful of slippery messes and spillages in the car especially (no one likes a smelly car!) There are better straw cups on the market than this one.

It leaks. Every time I have it my nappy bag, it leaks. It's done up tight but still water gets out. Annoying. I've used it at home & out and about and the same thing happens. Not sure why but it does. Very disappointing as otherwise, really like it. Oh well.
Nice size
Leaks.

I have tried so many so called non spill sippy cups. Most either cannot b drunk out of (even I had trouble!) or the non spill component has to b removed to allow drinking and then of course they leak.
This cup doesn't leak AND it is easy for little ones to drink from. And while the other nuby cups are great, I find the straw one much easier to use and my toddler prefers it.
Doesnt leak, easy to drink from, dishwasher safe so easy to clean. Also like the fold down spout cover to keep it clean between uses and no lid to lose!

This is a good non-spill straw cup for little ones, though it does spill some water out of the top on occasion. I started using this cup for my daughter when she was about seven months old and she learnt to use it just fine. I've tried all types of liquids in there including smoothies. Be warned that anything other than water is a pain to clean out of this straw.
Pretty much non spill. Easy to use
Pain to clean. Too many parts

I've had trouble with a few other brands, constructing them or them leaking. So I bought a couple of these and chucked the rest out. If you leave milk in there too long it can stick to the inside of the straw- solution? Use a chopstick to clean it, works wonders! Once I lost one of the pieces of straw, but I kept the straws from the badly designed ones for just this purpose- it fitted nicely.
I've recommended this brand to the twitterverse.
Me and my toddler can easily use it.
Milk can stick to the inside of the straw, but that's the same for any brand.

This cup doesn't spill and it stands up fairly well without toppling over. It is colourful and easy to wash. It also suits a wide age range. My toddler loves it. I love that I don't have spills to clean p. I also like that it doesn't look too babyish.
good quality and value for money

I am very happy to have found the nubby brand of sippy cups I use them at home and when I go to shops. My 2 year old throws drinks and there is no mess to clean up it saves me so much time.
It does not leak

I bought a few of these on special which made it really economical.

I love the bright colours and they are pretty easy to clean and keep clean. They rarely come undone in a handbag and even if they do, you have the advantage of the non-drip straw so you don't get leaks.

My child never had a problem working out the straw but some of my friend's children did.
Lovely colours, fairly easy to clean, easy for most babies to use, water tight and fairly well-priced
Some parents have reported problems with their child using it as it requires them to squeeze the straw before water/liquid comes out.

I have tried about 4 different straw training cups, and this one is my favourite. All of the others leaked to some extent, one i had to keep in a plastic bag if i was going out anywhere because it would leak all through my nappy bag. I love the colours (we have a purple one) and the design is awesome, my daughter can easily hold it without it slipping.
My favourite thing with this cup is that it doesnt leak! Lots of training cups claim they dont leak, but they do. I also like the design because it is easy for my 14 month old to hold.
Straw doesnt quite reach the bottom and the flip down bit for the straw doesnt clip in.

I wanted to get my son off bottles, he is now 16months, I tried giving him cups but he just poured it down his front so i thought this would be the next best thing. I love that they are non spill, my son knows how to open and shut himself
I think these are such cool bottles, you can mix and match colours and they are easy to hold onto. Great idea
I havent had any problems so far, though i dont like that there are so many parts, annoying to clean. I tjought they were also quite expensive, was hesitant to buy.
