CUPKIN Trainer Sippy Cup - The Original 8 oz Stackable Stainless Steel Modern Tumblers - Set of 2 Powder Coated Insulated Cups for Kids + BPA Free Lids + Reusable Silicone Straws (8oz Black + White)

Overall, the cup works well my only issue with it was it was easy for my toddler to pop the lid off. It does come with two different straws, a thin straw, and a thicker straw. The thin straw was easy for my toddler to pull out. I think it’s a great cup for a child that knows how to use cups well verse toddlers who are still curious about opening and closing items.

Love these ! My child loves tipping everything over . As long as you have everything properly sealed these tumblers are leak proof.I have washed them in the dishwasher multiple times and nothing has changed shape or effected the seals. Great for travel as well.

I wanted to love these because they are ADORABLE. However, my one year old throws these and the lid comes off and the drink goes everywhere! Also, it's hard to put the straw in after so I put it in the lid and put the lid on and no matter how much liquid is in the cup, it always comes spewing out of the top and makes a mess. Maybe when she's a little older it will be better but for now these are being shelved. They are the cutest little cups ever though.

Leak proof after you work the lid right. Only problem is the one I got is tiny. That's on me for not ordering the right size.

I’ll start by saying that I wish the cups were dishwasher safe and that the straws opened for cleaning purposes but otherwise they work great. We mostly use them for smoothies for my 1 year old. I’ll admit when I first opened them I was going to return them because they were smaller than I was expecting I guess but they do seem to be the perfect size for toddler hands and tummies. I love that they will grow with her and be something she can use for years and they do seem durable.

These cups are great. They don't leak. But when you put the lid on, the milk or liquid will squirt out the top of the straw due to the pressure. So you have to put your finger over the straw while you're pushing it down. Only thing I can say that was not good, is the straw was cracked for one of the cups. Would have given it a 5 star otherwise. Had to go to the cupkin website and order more straws. Hopefully no more will crack. They are made of silicone so it shouldn't have cracked.

My toddler is obsessed with my Stanley thermos. I went and searched for a cup similar that would be good for a toddler and stumbled upon these! They're great! They're insulated and help keep the drinks cold. We put milk in it occasionally and I don't stress if he's drinking sour milk anymore. They aren't completely leak proof. You have to have the lid snap open to be able to drink out of the straw ( which makes sense ). So if it gets dropped, there's usually a spill. The only thing I'd want to add is a handle. It's a great cup and I bought my nephew some! I'd definitely recommend! I'll for sure buy the bigger ones when he's a little older!I bought these 8 months ago and they updated the straw holder piece on the cup and sent me replacements! Free of charge!!! I didn't think it would make that much of a difference but it does! He can hold the cup from the straw and the straw stays in place now. Crazy awesome. I can't recommend these enough. They seem to be a good customer - caring company which makes me like them even more. I'm a sucker for some good quality customer service. It's rare these days!

I wish Yeti made cups like this for toddlers, but since they don’t, these are the next best thing! They’re very cute, I like that they’re not plastic, but they do leak from the straw area. Best to be used by an older child that knows to not tip the cup over. We use these supervised and mainly for water so the leaking doesn’t concern me too much!

The cups are easy to hold and made from good quality materials. They are not flimsy. However the top cover of the cap has a little flap for fastening the cap to the cup. That flap opens up easily and doesn’t fasten properly so the cup leaks and the juice spills from the top when the cup is tilted. Otherwise it is v good. Also please note that the cap and straw are not dishwasher safe.Am happy with the cup overall

Good quality,love the look. Got it for my 2 year old, but my 6 and 7 year old like using it too.

i bought this for my toddler to drink his milk and i love them. Beautiful colours,the lids seal very well and the straws are great and easy to wash.

I've been using or had experience with double walled insulated cups, flasks, etc for more than 50 years and use them everyday so know a little about quality in such products. I also have a background in Health Visiting, children's nursing, and those 'looked after' and I have 3 grand children and numerous nieces and nephews so I know a little about the suitability or non suitability of certain items such training cups bottles for toddlers and young children.In the context of my experience I do not recommend this cup for for toddlers and young children for the following reasons 1) The lid spontaneously pops open with warm drink in the cup creating a major spill hazard. 2) The straws leach chemicals from the rubber itself apparent in taste and smell. 3) The poor design of the lid mean you can't suck through the straw hole unless you open the sippy hole creating to open holes and another spill hazard. 4) The hinge flaps are very very weak on the lid and the stopper rubber can easily be pulled out by a toddler and lost or worst still swallowed. 5) The rim of the cup is very thin, unrounded and sharp for little (or even adult) mouths. 6) Without the lid the lid at £26 the cups even though robust do not represent good value for money. TheDUOLE, 2PCS Mini Small Thermos Travel Mug is exactly the same size in 5 different colours and at half the price £13.94 represents much better value for money. Even better in my humble opinion is the Melitta 6758256 at £4.95. I have given more details of the issues I identified with the CUPKIN cup below.UNSECURE NON SCREW LID SELF OPENING WITH THE STEAM FROM WARM DRINKS:The lid does NOT stay on CLOSED with warm drink! Rather, the steam from the drink forces the lid up and open right in front of your eyes because IT IS NOT A SCREW TOP which I Knew before purchasing. What I did not expect was for the rubber gasket to hold so weakly with warm to moderate drink. The seal is so weak and unsecure that even when it was empty and I put the lid on without drinks in it and the lid was SPRINGING BACK OUT with both holes open that all I could think was that a toddler with flip this lid of in a second. I actually saw a very short video clip of it happening on youtube but thought it was jus a 'one off' that somebody had filmed as a joke but it's not. PUT WARM TO MODERATE DRINK IN THE CUPKIN NON LEAKING CUP AND THE LID SELF OPENS unless you open the straw or sip hole and still it incline to shift back out. Otherwise a toddler can easily flip the top open and be soaked in second.THE STRAWS SMELL CHEMICALLY AND LEACH INTO DRINKS:The straws smell and taste of TOXIC like chemicals and the smell or taste cannot be removed by washing it. Just try it for yourself PARENTS if you have bought one already. Smell and taste what you are giving to you children. Initially I thought I had not thoroughly rinsed the washing up liquid of it because I got a strong funny tase in my mouth when I drank with the straw. Then I remembered I DONT USE WASHING UP LIQUID. I actually used tiny amount natural non perfumed soap, then thoroughly washed the straw with a straw brush with warm water. Neverthless when I smelt it again it smelt almost like non bio strong concentrated clothes washing gel. I soaked the straws in soda bic but the same taste and smell came through. It's actuall the rubber/silicon that the straw is made from so the smell and taste does not go away. I use silicon straws for hot drinks all the time and NONE smell or taste like these CUPKIN straws. TRY IT before you get bequiled by the 5 star reviews and end up focussing on the CUTENESS of the cups BEFORE you put those straws in your child's mouth.NOT POSSIBLE TO SUCK FROM THE LEAK PROOF STRAW HOLE:IT IS IMPOSSIBLE to drink from STRAW HOLE if the SIP HOLE is closed due to the vaccum that the suction through the straw creates. So you have to open the sip flap in order to drink. This defeats the idea of a leak proof cup and negates the necessity of having 2 holes in the lid (2 weak points instead of 1). If you use a straw through the sip hole is sufficient without the need to open the straw hole so the straw hole is a superfluous and uneccessary weakness especially if you loose or break the rubber stopper (think toddler) and worse still, dangerouse if STRONG little toddler fingers pull the stopper off and swallows it.BUILT WEAKNESS IN THE LID HINGE (I GUESS THIS ENABLE THE COMPANY TO SEEL MORE LIDS OR BRING OUT AND UPDATED VERSION):The 1mm plastic hinge holding the sip hole cover is terribly fragile and WILL NOT withstand drops, throw and the general pulling and tugging that toddlers do.NARROW SHARP DRINKING LIP HAZZARDThe OUTER edge of the drinking lip is NOT VERY ROUNDED but rather QUITE SHARP, much sharper than any I have EVER used and I have many cups like this, SEE PHOTOS. I nearly cut my finger on the edge of the cup when I was washing it.The cup itself is very robust but and aesthetically and ergonomically pleasing but I DEFINATELY DO NOT RECOMMEND this cup especially at such a high price. In a very short while THE LID WILL BE NON FUNTIONAL and you will just have a (albeit nice but just a) cup unless you buy another £7 lid.If the CUPKIN lid weaknesses are an issue then CONSIDER buying the EXACT same pair of cups (and buy your own straw) with a different (not necessary better but no worse) lid for half the price on Amazon - see item: B099KBFHT8MUCH MUCH BETTER STILL (in my opinion), If you don't mind something with 15mls more capacity, a little taller but SMALLER DIAMETER GIRTH than the CUPKIN cup, BETTER for little hands, much safer lovely rounded and thicker edged drinking lip, A ROBUST SCREW TOP LID with a much less TOTAL SPILL RISK, much MUCH STRONGER SIP HOLE CLOSURE HINGES, NO ADDITIONAL UNESSESSARY HOLES IN THE LID A STAINLESS STEEL BODY, BUT ACTUALLY LIGHTER THAN THE CUPKIN THEN I HIGHLY RECCOMMEND THIS ONE ON AMAZON - B01EALG48G for £4.99It's the Melitta 6758256 Thermal Travel Mug. Most of the negative reviews are because it's TOO SMALL (250 MLS for an adults drink cup) or that it does not hold the heat long for a travel cup, both points of which are POSITIVE for a child cup. Brilliant. Best of all it is only £4.99 see photos of the red cup

These are gorgeous cups, and are a great idea, but unfortunately poorly designed and just not ideal for toddlers at all. The cup didn't last 2 days with my 14 month old: he dropped it once and the pop-up lid snapped off and broke. Other issues were:1) The lid is not very secure and when my toddler dropped it (accidentally, not with force) it came off and contents split everywhere (once with water, and once with smoothie!!).2) We noticed that my little one could only get a few sips in using the straw before it would stop working and he would get frustrated that the water wasn't coming through. Both my husband and I tried to suck from it and didn't work for us unless we let some air in by opening the lid a crack (this is so counterintuitive to have the lid slightly open when a toddler is using it (spills spills spills!!).Quite disappointed in all honesty, and just not worth the price.
