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.

You do not have to bite the straw for the liquid to come up. My grandson had no problem with this cup and has used it for about 6 months (he is now 23 months old). He still has this cup but his other plastic zippy cups with straws have been replaced with stainless cups.

No straw U just push a button and it opens I loved mine and bought 4 but after closing the lid too tight I guess too many times (granted im 90lbs) and running thru the dishwasher 4-5x the lids all started leaking, cracking around the rim

Yes. Mine leaks horribly! Even after she drinks out of it and I relieve the pressure. The milk always creeps up the straw. I sent the company an email about it and am awaiting a response.

No, only a hole to drink from. But I had same thermos for 20+ years before the lid started to leak so if they are made even half as well you'll get plenty of use out of it. But no hole for a straw!!

As long as you have the top on tight and the straw top closed I'd consider it leakproof. That said, I have had mine leak if the straw portion wasn't shut 'just right'.

I have a 40 oz Hydro Flask with the lid/straw attachment and I have not experienced any problems with leaking while the attachment is in the closed position. If yours leaks, you may have a faulty attachment.

No. It is not leak proof when the straw is in the lid. It is leak proof when the straw is not in the lid. The leak is a slow dribble, so if you knocked it over by accident it wouldn't leak very much.

the lid screws on and you have to flip the straw upright to drink. I have not had any problems with leaks and use daily and throw in my lunch bag. I like this bottle because keeps smoothies cold through the afternoon.

Yes. You would have to put the straw in the lid opening. Just remember, this cup is not spill proof. If you turn it over, the liquid will pour out.

No. You must depress and hold down the lever on the top of the spigot to open the valve and then release the lever to close the valve. You can also lift the lever to an upright position which will keep the valve open without having to keep holding it.

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

If you start with a very cold drink, the pressure inside the cup will change as it warms up and will leak out the straw a little. Unscrew the top and pinch the straw open to level the pressure again and then tighten it back up.

Yes. You twist the top part and the straw retracts to keep liquid from spilling out.

Definitely. You use a self-sealing dispenser "pro" gun that gives MUCH more control of the application and shut-off process. It eliminates almost all waste and mess. I will never use a straw-type again unless there's no other option or I know I'm going to use up a whole can in one spot.

No, I have never had a problem with it leaking. Try to keep it upright. Make sure the straw is down.

It does not leak out of the lid or the rubber grommet. Its a water tight fit. The straw is hard to get in the grommet tho. You have to get it wet first and twist it while you push it in the lid. Liquid will come out of the straw tho, but that part is expected. We love the lids.
