It does have two holes in the lid. A sip hole and a vent hole. It is not meant to be turned upside down. Most hot beverage holders will have some way to vent the steam, unless you get a thermos type container. I hope this helps. It is a handsome mug, nevertheless. Thanks

Yes it will leak. Only good as long as it is upright. The top has a slider type opening.

It's leakproof and you can flip it upside down without leaks. This cup is amazing and keeps your drink warm for over 2 hours.

It is very tight to turn, but it will. Use some vice grips or pliers until it turns loose then spray some WD-40 on it. Mine is very tight and hard to turn every time I use it but it doesn't leak so I'm happy.

Yes it does. I tested it out by holding it upside down and nothing leaked out.

If you hold it upside down and shake it a lot it will leak, but we've had no problems with normal usage. If it falls over nothing comes out. You may get a drip or two if you hold it upside for an extended period of time, but I don't know for sure. We haven't had any problems with normal day to day usage and we've got 3 kids (age range of almost 2 to almost 6) and they each have one.

It is leak proof as long as you put the tab in the "lock" position, and have it assembled correctly. I throw mine in my backpack and the only time it leaked was when I forgot to lock it.

Good question: I have never turned my filled thermos upside down to make sure it does not leak, so I cannot give you a definitive answer. You might try the company's Internet and ask if it is indeed spill proof, etc. I now intend to check all three of my thermos containers when I wash them to determine how they stand up to rough/normal use. But it will be a few days before I take the time, so maybe you can check back with me?

I tested each one filled with water. Two leaked, one didn't. There are always slight differences in items like this. If you are going to turn them upside down or sideways, test each lid first to make sure.

You can definitely leave it and not worry about leaking. Screw the lid on properly though!

Did not leak on me, but I kept it level and did not turn sideways in my lunchbag. Fairly tight seal, but if jossled too much might pop off.

As long as it remains upright then it will be fine but it will leak if on its side

Ive using mine for about a year. It can be rotated and moves if you turn it. As long as it doesn't leak , I'm ok.

I fill the water container in the kitchen sink, then screw the black part on as I would any jar lid. Then carry it outside upside down. Only invert it when I'm hanging it on the hook in the tree where it lives. Doesn't lose much water at all, as it simply fills the little bathing/drinking cups as I invert it.

Yes it will leak. I have carried tea in it to work and had this issue. I now keep it upright.

It doesn't leak at all. Very leak proof. I often place it in my purse where it is tossed and ends up upside down.

Yes as long as the gasket is in place and you completely screw it tight, it will not leak! I've turned my upside down many times or it has fallen and nothing leaked out.
