is this a "spill proof" cup / lid?

I wouldn't call it spill proof because there is a hole where the straw goes that would leak if it were on its side. That hole can be slid shut, but still not water tight. I'd call it spill resistant.

One of the best I have seen. You have to open it some to drink it is so tight.

It is pretty much spill proof. I've knocked mine over with no spills. If held upside down the liquid would come out.

Yes and no. It screws on very easily and very tightly. But it can leak around the straw. Once I put in in my purse when my hands were full (don't ask :-0). The inside of my purse got wet! Even so, I love the cup.

This is not a spill-proof container. The lid uses gravity to open up and allow you to pour. When sitting straight up, the lid "rests" on the opening.

No! The lid has a hole that does not close (it's a screw on top, but you can't seal the actual opening where you drink from). Even if you did find a plug for it, I wouldn't trust the lid to stay put, and this is a glass tumbler, so it is VERY fragile. I accidentally dropped the lid and it shattered, so I had to buy a second one already. You need to be VERY careful with this item, but it is extremely elegant and for that reason I love it regardless :)

I really have no problems spilling. I do hold the end of the lid with my thumb just in case it decides to come off. Hope this helps you out.

No- the lids stay in place well, but it's not leakproof, so if there is any liquid, it will spill through. Best to keep flat

Honestly, I leave this cup in the office so I removed the lid and don't know where it is. If my memory serves, the lid did allow sipping and is spill-proof. I just can't confirm it 100%. Sorry.

No as long as the lid is snapped on tight it does not spill. If the lid is a little ajar, it will dribble a little. So make sure it's snapped on and that should fix the problem.

Unfortunately I'm not sure.... I've never spilled anything in it, yet at least. I used it to hold work materials in my truck for work, so I cant speak to its leak-proof ability.

Sorry, nope - it will leak if you shake it and it's full enough to collide with the lid area

It does not. The lid is one solid piece like a jar, so after removing the lid its similar to drinking out of a mason jar with a tea strainer. So when the lid is on its spill proof but when you open it to take a drink it is just as spillabe as any other cup. I do not find this to be a problem and i take mine everywhere. With the lid in place i can throw it in my purse or diaper bag with no worries.

It's going to spill if the top is not on, but other than that- no. If it's tightly closed then no

Yes, it has two sealed openings, one on each side, so you can drink either left or right handed. Autoseal makes the cup spill proof.

No. It is spill proof by being weighted in the bottom and the funnel like shape of the spitoon prevents spillage. Mine sits perfect on top of the cup holder in my truck

Not at all. However due to its geometry, tilting this cup to drink takes a bit getting used to due to the light liquid pressure from a smaller volume at the short vertical top section. Also it does not seem to maintain temperature as long as my previous thermoplastic cup. But for durability and spill avoidance, it can't be beat. It is highly unlikely to accidentally knock this cup over when reaching for it without looking.

Yes, it is completely leakproof, which is awesome! There's a way to lock the lid out too so that you can't squeeze the button and let the liquid out. These mugs are the best!

I shouldn't leak at all if you have the lid snapped on firmly and the little vent hole cover snapped into place. It's a rubbery lid that seals pretty tightly and takes some effort to sort of "peel" it back off the cup when you are ready to eat. I've never had any spillage in my fancy tote bag I haul lunch in.

Yes! I have knocked it over and never a dropped spilled. Inside the lid there is a thin waxy like substance that when you put hot liquid in activates sealing it. If you tilt it while it is full I recommend waiting a moment to open it though as with the metal mesh strainer inside it takes a moment to drop back down into the cup.
