I've been trying some different cups lately and this one went in the garbage. We would carefully line the nipple up with the ring and make sure the whole top got screwed on perfectly. I would even shake it a couple times over the sink to make sure everything was assembled correctly. Even with all that, my daughter would start drinking and half the time her drink would start pouring out where the ring connects to the cup. Waste of money! I have liked a cup made by Munchkin that looks very similar to this one (soft top).

My twins quickly found they could push the silicone spout inward and make a puddle to play in. And one good chomp and they were useless. I only bought 2, but will never buy another. This is so disappointing because Nuby makes some really good products.

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.

I do not care for these sippy cups. The top part that they drink out of has small spaces that are difficult to clean out. I also had trouble with them leaking.

Cheap..but the nipple on these gets sucks in and wont release once my toddler drinks out of it once...its the oddest thing.. i have to open the cup to release the suction so the nipple pops up.. she can pull out the nipple and gets herself covered in milk/juice all the time.The nipples are super hard to clean, milk can get stuck in the spout part.. i use q-tips to clean it but that;s a waste.. they need a redo of these cups.

I threw all of my Nuby cups away and replaced them with Playtex cups. I thought I would like these because they were BPA free and inexpensive, but I had so many problems with the nipple collapsing on them and the would leak everywhere. Milk would literally pour out of them if you didnt have it on perfectly and they were a pain!

I did not care for these at all. They do leak / spill. They did not do well as training cups for my daughters. They bit/chewed on the top which made them just spill all over their clothes. The hard tops work much better for us.

These things leak like crazy!! I'll only use them if I want milk all over my couch!

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

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.

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

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.

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

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

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.
