Do these cups leak at all - either through the drinking area or around the rim?

No, no when used normally. Some will leak out when child chews the hole bigger or smushed it onto something or throws it.

Not at all! We had had for 6 to 7 months and not 1 problem at all. Our son did bite through 1 nipple because we didn't pay attention that he was teething, but that is what can happen with any bottle!I give it a 9.7 out of 10 because I wish they had more schemes other then the two we have found available. It would be nice to have different patter or colors to tell if one is a juice cup and one is a milk etc.I say buy it, you will love them!

Mine have only ever leaked when my child has chewed on the spout & created a larger hole in it. Otherwise, never & I've been using them for about a year.

They don't leak anywhere. Only cup I have found so far that truly doesn't leak a drop.

The cups are thick plastic. The plastic is not thin like a Play-Doh container. They would definitely hold water, but I don't know about being water safe. Sorry. There are no numbers on the bottom of the cups to help determine the type of plastic and I threw the packaging out long ago. Hope this helps.

They are! I am still amazed by this - even after going through the dishwasher! I often bring soup or juicy fruit to work and it does not leak. Hope that helps!

Besides the nalgene cups, these are our other go to cups. The only time we've ever had a leak is when I had the top screwed on wrong. I did purchase the lids for traveling. I do dishwash them on the top rack with no problems. Hope this helps!

They have been known to leak. I have discovered that if I heat the lids before tightening, the plastic will become malleable and I can tighten them further. Then, when they cool, the plastic shrinks and the lid will be tighter and not leak.However, just for picking up and shaking a drink, I have not had a leak with something like that. When they leak usually it's a very small seep.

They have a lip and a diamond shaped hole to sip from. This hole does not close. I really like these mugs and will probably order more. They are solid and sturdy with a great handle, too.

No these are an open cup design that leaks sound out. You want a closed cup design instead for more sound isolation.

I have no idea since I have returned them. They leak allover when pouring liquids.

I've had no leaks. I carry one in my bag ever morning and no leaks. They are super sturdy lids, they snap closed really tightly. Does not come with a straw. Highly recommend them.

The round ones have a tight lid and so they don't leak, but the rectangular ones don't close that tight and so they leak. On the first set I got, the small rectangular lid was way to loose and they sent me a new set. The lid on that one fitted a bit better but it is still not hermetic and leak. I had to go and test them after your question so now both you and me know! :)

Well, neither really. You push them on and there is a rubber ring that creates a seal. Does that make sense? It does create a nice tight seal that won't leak. However, on top you will either have the straw opening or the sipper side open. The plastic piece slides back and forth to expose one or the other, you can't have both sides closed. So, it's not going to leak on you as you drink, but you won't be able to throw these in a bag and go.

I have never had them leak and I've been using them for a year now. I've put fruit in them and the juice has never leaked. I own 3 sets of these containers and love them! Now that my son is getting bigger, I wish they made them in a bigger size.

Absolutely, in my opinion. I have been washing my cups exclusively in my dishwasher, and they are still watertight. One of my older cup lids (4+ years) has had the silicon gasket come loose, and I just shove it back in there -- no issues with leaking.

No it doesnt leak, maybe a drop or 2, i have the same problem with my kids. It's a good cup for kids.

Kind of but not really. Also I wouldn't recommend them because of the sharp edge around the lip and that everyone single one has cracked on the bottom. They don't leak but I still didn't expect them to crack

I haven't had problems with leaks yet. My kids love these...don't fill them up all the way otherwise when u close them it will spill over.

I use them in my drinks. I have had a few leak but they are safe. I use them every day.
