I bought 1 of these a few months ago and it was leaking, bought another one to give it another chance but it got worst! Bub can't sip anything through the straw! I tried sipping and i got air. Though I like it because of its tall design and removable cup cover. Not buying this product anymore. :(

Can't fault these cups except the rubber from around the mouthpiece can get a bit chewed and start to wear away after a while. I've noticed some people have had problems with leaking though and would like to make a suggestion. If you pull out the valve you will see there is an oval section which the straw goes in and if you flip the while valve over, across the back there is a rubber band which sits over a hole. This sometimes gets displaced which causes the cup to leak. Simply flick it back over the hole again and it won't leak.

My toddler used the Heinz Basics Trainer with great success. So when she was ready, we upgraded to the Heinz Baby Basics Toddler Straw Cup. Unfortunately, this product has been a waste of money.

When my toddler was unable to suck anything through the straw, I tried without success. The amount of pressure required to suck anything through the straw makes it impossible even for an adult. Perhaps I was unlucky and got faulty cup but that's not acceptable. I would definitely not recommend it to anyone.

Unable to suck anything through the straw

My daughter has used this cup without issue since she was 11 months old. Has never leaked (make sure you use the anti-leak valve properly), even when thrown around, tipped upside down, etc. 2.5 months of use and it is starting to show signs of wear from teeth so I am going to buy another one. Overall, really good.
No mess!
Starting to show some wear after 2.5 months

I bought this cup as I really like Heinz products but unfortunately it leaked from the screw top regularly. When filled to over half way it would leak right through my nappy bag, even when standing upright. A slight tilt in my nappy bag would mean the water would come into contact with the screw top and somehow manage to escape. This was very frustrating as on the first occasion we were travelling and all 3 of our passports were water damaged. I thought I must have done something wrong so I continued to use it however it kept happening.
tall cup that didn't take up too much room in our nappy bag
leaked like a sieve

I bought this cup after having had other heinz products that were great. I put some juice in it and it leaked all through my nappy bad, and it was stood up! Very disappointed.

Leaked. Don't recommend buying

not a cup ide buy again given the problems i had with when fluids got low and the drink not going up the straw, is easy to clean and hold though in little hands
i brought this for my toddler and found she had problems drinking out of this, she would need to tilt her head back to drink as found the straw often wasnt adequet enough when drink was getting low. we took the straw bit out and it worked better for her, although given the cost of the cup i probably wouldnt buy it again. it is easy for her to hold and grib and i didnt have problems cleaning it
the straw when fluid got low made drinking a little hard, often our daughter would play with this cup by oening and closing the covering lid
