Are they leak proof?

I would say they are leak proof as long as the top is on correctly. The top can be a little tricky because it isnt really flexible so you sort of have to force it on but i would feel confident that its a leak proof container.

I have to say yes. While I haven't put any liquid in mine, the truly secure way the lids fit would indicate a leak proof seal. The lids will be very tight, almost too tight the first time. I them in warm water to soften and have had an easier time since. Lids are still very tight, but that's how I want them.

Yes, they are. They are wonderful. I use them for medicines, condiments etc. They last for a long time too, without staining and peeling.

Yes, I use one to carry my coffee creamer to work every day and it has never leaked.

Yes they are. I have worn this through some very tough, heavy rainstorms without any leaks at all. So far, so good!

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

If you tighten them well, they shouldn't leak. I have noticed that overtime the gasket wears slightly and the seal isn't perfect but tends to leak only when the cup is dropped.

I used these at a wedding for holding sparklers before and after they were used so sorry do not know if they are leak proof. I would suggest a liner to be safe.

I have not had them leak as of yet. Just make sure you get the plastic roller insert in tightly.

They are very well made and seal tightly. I'm not sure they are air tight, but they are leak proof.

I never had an issue with them leaking and I used them everyday for six months. The only problem would be if they are overly full then frozen, the top won't stay on then. Just don't fill to the very top.

Well, no, they do not leak, but they can get very heavy if you use them as a toilette. I should not say this, but you should see an Urologist and use this in case of an accident.

No problems with leaking and I have had mine for a few months now. They work great! I use them not only for my baby chicks, but for my adult chickens. It conserves water and the chickens have fresh water by using them.

I would say they are. Have two of these and commonly leave them laying on the side while traveling in passenger seat and in my lunch box haven't had a leak yet

I have found them to be mostly leak proof. On occasion I have overfilled the soup container. When I do that there is a bit of soup in the bottom of the warming can. It is a case of operator error.

They are leak proof & water tight. They're pretty durable but the lids are susceptible to cracking if you crank them too tight too many times. Also, I noticed after about a year when the kids (accidentally) dropped them on the ground the bottle itself cracked. I suspect this is from rugged daily use & dishwasher cleaning. I think the extreme heat from the dishwasher dries out the plastic. Even with this happening, I've been happy with the bottles. Hope this helps.

I have had these for going on two months and have not had a single leak. I use them for our two little girls almost daily!

I have not had any problems with them yet. I even put coconut oil in one of them with a lid and keep it in my swim bag. It has not leaked yet.

I cant promise that they are leak proof but definitely leak resistant. If you knocked one over upside down their might be some slow seepage but not much and no real mess to clean. The heavier the liquid the safer you are. Water itself might leak out but probably not soup!

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.
