We bought these for my son to switch him off his bottle. Theyre cheap in price but still leak. Whichleft my couch many stains:(

I bought this cup for my son because it looked like he would be able to drink out of it better. Well I've had to buy a different set of cups because be would hit the spout on his highchair tray and THEY LEAK! I would wipe up more of the juice than he drank. They're cheap but still not worth the money.

My nephew has these sippy cups. I do not like them. If they suck to hard the mouth piece caves in.

they Leak after the first use for me. I don't really like them at all. Very unhappy.

My daughter loves hers. It has spilled a few times and I wish the nipple wasn't so easy to pull off, especially with a curious kid!

Wasn't a fan of the nuby sippy cups, found they always leaked from the nipple.

I don't own one of these sippy cups but my daughter used one at a friends and it leaked all over. I think the hole was too large for her and she ended up getting all wet. I wouldn't go purchase them myself.

After a few uses, these always leak. I was not happy with the quality at all.

Good priced cups but they do leak / spill. They have not been doing well cup training my daughter. She gets milk all over her clothes.

Not completely spill proof and the cup is hard to clean down in the bottom.

Did not like cleaning these. And when My daughter was teething she would chew off the spout

Cheap to buy and that's the problem, they leak all over the place. I'd rather spend the extra money to buy something better.

Okay cup in a crunch, but it leaks. Also, the tip is really soft and silicon, causing lots of kids to chew on it and rip the mouth piece.

i tried and tried to like them but after a few washes the nipple wear down and the cup begins to leak. messy messy messy

These cups were cheap to purchase, but also cheap in design. The "rubber" nipples were easily destroyed and didn't clean well, and yes, if you didn't line them up exactly, they leaked. What bothered me the most is that there were no replacement nipples available. We have replacement nipples for bottles, why not these? Soon, the "cheap" bottles weren't so cheap anymore when you had to start buying new ones every time my son chewed through the top. Now I have a lot of these, but no nipples for them. So we made them into vases and pencil/crayon holders for craft time in the car and around the house.
