NUK Hide 'n Seek Hard Spout Sippy Cup, 10 oz, 2 Pack, 9+ Months, Unisex

Only a couple weeks of use and it is leaking. No, the plastic valve part is NOT broken or fractured or loose, bought 4 of these and they all were leak proof at first but just WEEKS of regular use and they are ALL leaking!? There were NO instructions given with cup so given that it is fairly easy to assume how to work this. Extremely annoyed having to bend down to clean up sticky juice or white milk off the floor at 7 months pregnant since both my toddler and baby uses these "leak proof" cups. Officially done with this brand.

We have been using these sippy cups for quite some time, my daughter loves them and I love them because they're usually spill proof! Well I bought a pack of 2 yesterday and used one today and the inside clear part on the top goes in all the way (like it is too small for the hole) and the cup is leaking ! Upset because my daughter loves to “finger paint” when she finds a cup that leaks, so I'll have to discard the cup.

I received this nuk active cups as a free sample and they work very well for me. They are sleek and very light and do not leak. I do wish it had handles for easier crip for the child. The clip on the top of the bottle is very useful when traveling because i can clip it to anything

I received sample of this product was easy to put together. Great for drops, it did not leak. It did not work well with my 2 year old. He is used to a softer spout. The drinking spout was a little hard but that is great for durability. I think it would be better received if the spout was a little more flexible. It is a great size for a 2 year old and holds enough fluid that we do not have to keep refilling it frequently .

I received free samples of this sippy cup to review, and I really enjoyed it! Any toddler cup I have ever tried always leaks, and I have never experienced this one leaking. I would definitely recommend it to a friend! It makes it so easy to fill up the cup and take it anywhere we are going.
