NUK Evolution Straw Cup, 8 oz, 1-Pack

I always buy nuk. I was raised on nil products in Europe and when having my own kids mom suggested this brand and I always stuck with nuk everything for my 2 kids, I have just purchased the new straw evolution cup and it seems that the straw has some sort of blockage and as I read thru I see people have this problem often. Is this something that can be fixed on my own. Again I love ur products this is my first time dealing with a negative outcome

The straw design is TERRIBLE! My 2 year old kept giving me the cup back asking for drink when he already had something in his cup, I tried to sipping from it and nothing was coming out. Ended up having to stick a knife in the two air holes in order for the cup to work. Definitely not worth the price.

Doesn't leak but nothing comes up. Do I need to cut the part that hooks to the straw? Don't want to ruin it and no instructions say to do this but even I can suck any liquid up. I'll change my rating if I can get help!

I bought 2 cups for my 20 month old daughter, she only drinks her milk with this cup. One straw broke and the other is almost gone (my daughter bit it)been looking for replacement straws. Do you sell replacement straws anywhere? The cups are in great shape, straws don't last long.

Love these cups but the straw can be bit through very easily and they DO NOT sell the replacement straws and you must buy a new cup. Not worth it in my opinion.
