Do the covers keep the cups from leaking even a little bit?

I did not have any problems with leakage. I have used them for transporting pickles, making jello shots and putting condiments in to take for lunch.

Yes, the lids seal up nicely. I just tried it out to confirm and water doesn't drip out while holding it sideways or upside down. The lids seal it up tight and no spills.

unfortunately, in my case, they don't. you either need a snug enough bra (which isn't ideal if you're breastfeeding) or you really need to make sure they are centered nicely, so if they move, the pad can still absorb the leaking.

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 haven't had anything leak through when using them... They hold a lot more than you think they would.

I never had any leakage problem with theses pads. They should hold 4 cups - they are very good pads as I have tried many brands.

We only ever use the straw valve and the straw, but I only give my daughter water in these so I don't worry too much about leaking. They will leak out if tipped upside down, but I still really love these sippy cups and we never leave the house without one.

I have had a little issue with the casserole lids not having a tight fit after being used in the microwave. I have not had any leaks taking them to work, but I don't really challenge the seals either as they are always in a lunch box and not bounced around very much. The cup lids still fit tightly.

They seem to work when tapped on the side or pushed up. Even being able to do this I haven't noticed any leaking.

Generally they do not leak, but a couple of times I haven't gotten the nipple in straight and then it does leak.

I have not had any issues with leaks. My wife hasn't had any issues neither and she uses hers for medicine, make up, lotion and other liquids. She also keeps some in her purse and they have never spilled. She carries large purses so these containers really get bounced around.

The cups themselves? Not really. ..they stay great inside the round canister. .

The tops seal pretty tight and there is no spillage. We lay them down, so far there hasn't been any spillage.

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!

Yes, I just went and double checked and no leakage. I've had them a couple months.

No, it doesn't need a cover. Once the inside-the-top sipping/sucking regulator is tightly in place - no more difficult than putting the nipple and cap of a baby bottle together- and the top is screwed in place, you cannot make these cups leak. The only ones I've ever tried that really truly work!
