Is it true that you have to open up the straw and put in a valve every time you want it not to leak when out?

We only ever use the straw valve and the straw, but I only give my daughter water in these so I don't worry too much about leaking. They will leak out if tipped upside down, but I still really love these sippy cups and we never leave the house without one.

To be truly leak free, yes. I generally only fill this wonderful sippy half way and then when tipped on its side, it won't leak as the straw will be out of the liquid. We have also been using this great sippy without the straw lately and leaks are rare for us.

You're referring to the travel plug which is included with the cup. I haven't used the travel plug at all. My son drinks all day long, so I don't worry about it. If you leave the cup alone for a while, and it's full, the liquid will rise through the straw and may leak onto the table/floor, etc. whenever I see that happening, I sip from his cup and it's a non-issue.

It pretty much acts like a travel mug. The lid screws on and you can cap the hole you drink thru/put straw in. If that is open, then yes, some of the liquid will get out if spilled. Overall, I have been very happy with this item.

the yellow mesh helps with the big opening. as for the straw i have seen athletes at triathlons glue them in place or use a rubber gasket "O ring" that you can find at any hardware store to help with the leak. I personally just let it splash, it doesn't seem to bother me but i and my bike get a little sticky

You can drink out of it like a sippy cup, no straw needed, but it is not leakproof. It helps in the spilling amount, more so with the straw.

No that is the best feature. You have to squeeze a know before the liquid is released. I haven't had not one mishap.

It does leak with the straw out. This is the one cup I can't give my kid for bedtime as it will make a mess if it's tilted.

No, you do not have to use the straw, but you could not tip this over and have it pour into your mouth, as you have to "bite" onto the spout and suck the water. It is essentially leak proof though.

No it doesnt. Now if it gets hot the pressure builds up and some will come out the straw but thats it

No not really. It'll leak a little if knocked over when straw is in place. I take it on the go without the straw in place. You can either take the straw separate or leave it behind & just drink straight from the top with the lid off. If you buy this product you won't be disappointed, it's the most used thing in my kitchen. I LOVE IT!

The straw has a stopper that is closer to one end of the straw. I use the straw with the stopper in the cup to keep my straw from coming out of the top, but I have seen others use it toward the sucking end of the straw ... guess you can do what you want. But mine don't move from what I can tell. Hope this helps.

Yes- there is no rattling and the straw stays in place. You can kind of tell in the picture there is a flap inside so when you pull the straw out it seals so nothing spills out. Best cup ever!

Yes, as a matter of fact, the spring loaded flap on the lid that closes when the straw is removed also keeps the straw from moving around on its own. I just shook an empty tumbler with the straw inside and the straw never moved or made a sound, even without any liquid in the glass. This is a great tumbler!

I love mine and it has never leaked on me. When I fill it then go to screw the lid back on, the water pushes up the straw so I just drink more of the water then screw the lid on the rest of the way and I've not had any issues at all with leaking. I love mine and I use it EVERY day....

As long as you close the lid they do not leak. The straw fits in the lift tab I do have a problem closing and opening the lift tab because I have arthritis and I'm old, a normal person would have no problem.

You have to unscrew the lid, I prefer it this way so it doesn't leak once it's closed.

Yes it does. As long as you close the lid so the straw does not stick up. Does not even leak a drop.

It is not leakproof- it would leak out the hole where the straw is inserted
