Stackable Stainless Steel Kids Cups with Straws and Lids by Cupkin - Set of 2 Powder Coated 8 oz Insulated Tumblers, 2 BPA Free Lids and 2 Silicone Straws (Blue + Green)

Very difficult to suck from, terrible for kids

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.

The crappy piece of rubber that is used as a mouth piece leak stopper falls off really easy & isn’t replaceable you have to buy a whole lid from the USA which costs more than x2 new cups from Amazon where they are not available separately. This is if they have stock which is unlikely as I’ve been waiting over x2 months now they tell me the above. I am receiving daily marketing emails saying how wonderful Max & his invention are & actually they’re service is pants.

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.

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