Does it leak? Is it easy to sip from while walking (without scalding my mouth)?

No it doesn't leak and it dispenses very evenly so you won't get burned. very nice mug. Get it

It does not leak from the seals, though there is nothing stopping the liquid from coming out of the sip hole if it were tipped over. It keeps the liquid very hot for a long time, it is easy to sip from though. I sip test it without scalding my mouth. I've really enjoyed just about everything about the mug so far.

It doesn't leak and is sippable while walking. Mine doesn't keep my coffee very hot though. One hour in the gym in the morning and my coffee's cold, even when I wrap it up in a blankie.

I have never had a problem with it leaking. Some reviewers say this is an older model with better features which was why I purchased it.

Yes its easy to drink from, it could be better but its not bad. It has like a twist nob on the top that prevents it from spilling and you just twist and sip

yes it does leak a little when turned on its side and the cap/straw is in the open position. The leak is several drops so if it is in a backpack or against paper, yes the paper will get wet. I use it as an adult drinking cup beside the bed - so it is great for me.

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.

I mostly use it at the office and upright but a few times that it fell or was laying horizontally - there was not a drop leaking so i think its pretty well sealed. Its also amazingly easy to clean - has this teflon style interior. I actually use Contigo plastic bottle for gym and it never leaks - just screw the cap on tight.

No. It leaks. I recently replaced this cup with "The Safe Sippy Cup" that I also bought with Amazon prime for 10.99 and I love the replacement.

Yes, my first one leaked so I bought another and the second one leaks too. I may return it, or just use them in the car where they will remain right-side up all the time. Also, even when upright if the mouthpiece is open then warming air in the bottle will push a LOT of water up and out of the straw and all over your cupholder area. So if you use it in the car make sure to close it. I'd never carry one of these in a backpack. Water does really taste better though, so I'll accept the limited usefulness.

The straw lid does leak. It is really designed to be upright. It's the one downside.

Though it looks loke the real lens cap, it does not have a hole or a sliding trap or something to take a sip. It is threadable, no leaking problems for me.It is good for desk & office use, not recommended for traveling since you have to remove the whole cap to drink fro it.

Yes-- it slides in and out very easily. It's easy to fill--just make sure you tighten the lid correctly or water will spill. I've walked close to 500 miles with it and love it.

It is a sippy. It comes with a gasket for no spill but its still easy to drink out of the two holes.

Well, neither really. You push them on and there is a rubber ring that creates a seal. Does that make sense? It does create a nice tight seal that won't leak. However, on top you will either have the straw opening or the sipper side open. The plastic piece slides back and forth to expose one or the other, you can't have both sides closed. So, it's not going to leak on you as you drink, but you won't be able to throw these in a bag and go.

So far mine has proved to be totally leak free! There is also a lock on the lid to make sure that the mug won't open accidentally.

It is rather leakproof, but if you were hiking and had this in your backpack I am sure it would open up at some point and begin to spill. I would recommend just using a thermos and a tea infuser instead.

I have not had issues with straw leaks unless it's held upside down for an extended period of time. I have a hard time getting water out after a few sips, but my daughter will guzzle half the glass of water before coming up for air! I think it's because it's built for infant/toddler mouths, not adult mouths!

I've only used it 5 or 6 times, but so far, no problems with leaking. I've only used it with warm liquids and I'm not exactly sure how long they stay hot because I drink it like 15 minutes after I put it in there
