Does the lid opening lock or close to prevent venting heat?

There are 2 small holes on the top: one to drink from and one to let the air in. They don't close. But this makes no difference for heat loss. This is not double-walled and the drink cools quickly.

No. The lid is literally a flexible rubber with a small hole to drink through. Very basic.

No...it's like the common cover you get in a take out cup.. You could stick a little plug in it like some if the take out places..

Not that I know. I and my spouse have no problem by unscrewing the lid a quarter turn to release any air when opening.

No it has a vent you open in the top, And a little plastic tap that you turn to open and close built in. It works pretty well.

Yes, the glass lid has a small vent hole to help keep lid from steaming up.

I always put the lid on. It guards against the occasional mini explosion that can send bits and pieces of food splattering all over the inside of the microwave. And, yes, the vent must be open or the explosion might be less mini!

You keep the vent closed while the item is in the microwave. When you remove it, open the vent to let the steam escape, then open the lid and enjoy!

Hi. The door seals tight, but there is a convenient chimney hole in the top center, about 1 inch diameter, where I always run my temp probe wire. Works great.

Yes. There is a little red switch on the inside that will keep the lid open.

The lid has a vent hole. To keep steam inside without escaping requires plugging the vent hole. You would have to be created plugging the hole.

Nope, the locking parts are stuck to the lid and sometimes flop down and get in the way a bit. They are supposed to fit in a little slot to stay put, but mine don't. Not a big deal and am used to it now. I think that they have a similar model without the locks though.

The lid locks very securely shut. It will not pop open if it is latched, and you can hear the latch engage when closing it.

Hi, if dripping out of the side of the lid, I don't think the lid was seated properly. Sometimes that will happen? I am always very careful to make sure it is on correctly by gentle moving the handle back and forth the tiniest little bit before locking in place. When the PC comes to pressure and the last steam leaves the pot through the vent and the lid is locked down, I have minimal moisture exiting from the escape valve on the top. Give it another try. I'm sure your Chili was delicious. I hope this helps.

No, it's like a pressure cooker lid. Turn 1/8 turn counterclockwise to lock and clockwise 1/8 turn to unlock. There is a pin in the cover that becomes flush with the lid when it is locked which is located above the left handle in the picture but not shown.

Yes to all except locking lid. It does have a tight fitting lid structure with a window and vent.

It does not block the vents. I'm sure it runs slightly hotter just based on physics :) but I have not noticed anything abnormal. I love the case so far (2 months)

Jen is correct, it's just a low vent on the back. It zips down if you don't want it open. But, it is perfect, when open, to put a fan in front of it and keep some fresh air flowing through.

I would microwave with the lid both off and on but not fastened closed. if u do not cook with a high temp, it will do less damage to the cup. I never used the vent but that must be what it is for (vent). I really like this cup with a fastened lid because I use a cane and can only carry things with one hand. if I were still traveling, this would be a perfect cup to take.
