Doe the cover leak down the front when drinking especially if condensation forms near the cup rim on the inside?

Does not leak. Cup not heavy enough. Does not keep coffee hot as it should.

No - I have two and have been very pleased. The lid is a "stretch to fit" silicon lid than seals quite well.

It seems to be as I've thrown cups of liquids away and it has never leaked. However, the lid is not.

Does it sweat? A little. Not hardcore. Just a little condensation on the bottom. And the straw doesn't have a cover. It tucks securely into the top in a groove.

If the lid isn't on just right, the seal leaks very easily when the cup is tipped. It doesn't leak much upside down though.

No I have not. But the lid screws onto the cup. I absolutely love the mug. Had it since Christmas and it has not leaked at all and completely seals after drinking.

no, I've recently noticed a little bit of leakage. Still like the cover, though but I'm not sure where the water penetrates from. Maybe it's a seam.

No, it doesn't need a cover. Once the inside-the-top sipping/sucking regulator is tightly in place - no more difficult than putting the nipple and cap of a baby bottle together- and the top is screwed in place, you cannot make these cups leak. The only ones I've ever tried that really truly work!

Not if it's upright, or the cap is on. Same logic as a cup. Does not leak from the bottom if that's what you my mean.

It has a locking lid. I have laid mine down and dropped it and it did not leak.

The gasket/lid would not leak. The small 'snap in place' cover over the drinking 'hole' could leak. It could possibly pop open and leak a lot. I have two of these and love them- freeze and use them every day. If you plan on holding it upside down over your laptop you might want to consider another.

I've had it for a long time, about 4 months or so in both hot and cold temps and have never seen any condensation or precipitation on the outside of the mug. I've been amazed with the form factor and performance of these mugs, they keep liquids piping hot or ice cold, never leak, are aesthetically pleasing and basically defy the laws of thermodynamics!

There is a little drinking slit and that is never closed - so it would leak if turned on it's side or upside down.

Mine has a button on the cover that pushes in to drink, so I can't really say. Loose parts in the stainless? Does not sound good. Are you sure you are referring to the 'vacuum' stainless? They do have other versions.

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.

If you're careful about closing the lid, it's definitly leak proof. I havent had any further problems once i knew i needed to pay attention closing it. As for condensation, that only happens when i refridgerate the bladder but i would reccommend having some sort of waterproof barrier between it and your electronics, to be safe.

Yes Deborah, there is a very small pinhole in the top. It allows air to escape when the lid is used. If the cup is tilted, very little if any liquid is leaked.

You have to close the little flap that covers an opening for drinking from, otherwise; it will not spill. If flap is open, it might spill contents, but slowly enough to not be disastrous.
