Are they leak proof?

Yes - leak proof from the actual spring form pans but if making cheesecakes you will still need to cover them in aluminum foil if submerging them in a water bath.

They are wonderful springforms, but I use them to make raw desserts, so ingredients tend to be thicker! Sorry I cannot help more!

If you are doing a water bath, no. You will need to cover the outsides with foil. Another tactic I have used is to place a large bowl of water in the rack below my pans (instead of doing a water bath).If you mean leaking batter from the inside out, I have not had any problems with that.

Yes. I have made cheesecake, carrot cake, and chocolate cake in these and never had a leak. The only thing is that it takes a little longer to clean out the tiny grooves.

almost no leakage. I've used them for years on-air with pretty heavy processing and no problems. Go for it.

I cant say much on this but I would say NO they are not leak proof or water proof the whole you suck the air out off I"m sure can get water in it, its plastic and I highly doubt its 100% proof.

They are very well made and seal tightly. I'm not sure they are air tight, but they are 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 only use them for water, but simply put - if you close the lid and turn it upside down nothing comes out. So I would assume no matter what liquid you put in there it would not leak out.

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'm not sure. The ones I've used never leaked. I'd contact Amazon if I were you.

Yes. However I would not recommend them. They started to leak after few uses.

No, they don't leak as long as you have them pointing up. We use them for demonstrating hydraulics with plain water.

I don't actually know for sure,but I do believe they are air tight and leakproof because the seal is very tight around the dish. Just make sure when you wash the seal,to let it air dry completely,or stretch the seal outward towards you to wipe clean&dry. I had an experience where I didn't wipe dry the seal and had to throw it out because it turned black. But I do think they are good and air tight and leak proof. Good luck,and I hope this has helped you.

Yes they are as long as you have a secure latch. If the latch isn't locked there is a chance of leaking. I placed 15 pounds of weight in the box and submerged it over night in a tub sitting upright and no leaks. Hope this helps. The other answer about the handle is very true it is completely water tight.

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 have had two for a couple years now and have never had a problem with them leaking. I am super hard on them as well

As stated in several reviews - they are not leak proof. We've spent too much time cleaning lunch boxes, car seats etc.

They are and worked great without leaks for me. Make sure you have the snap on type water bottle top.

I do use mine but they do leak. I am hoping they improve the seal. But I love em and use them...I just make sure i hand wash them and NEVER let them sit in a sink full of water and NO dishwasher.
