is it leak proof if left on the side?

I have not had one leak yet. I lay these bottles on their sides in my daughters lunchbox.

It does not have the sign, but it doesn't leak.I use it for my kids' lunch boxes almost a year, ( my kids in middle school)Those bottles didn't leak at all.

I have not had any problems with the bottles leaking when left on it's side. Hope this helps!

We have not had an issue with it, except for one time when my daughter did not put the lid on correctly (wet bookbag, homework, a huge mess!). If you can sit upright it's safer but if you practice screwing on the lid with your child it should be fine.

It's definitely water resistant and washable, but since it has a non-adhesive backing, it won't protect you from a serious leak as water can get underneath it along the edges.

no leakage unless it falls over with the spout open ... occasionally some condensation but not always.

I have had no problem of spilling when tipped. However, I would probably store it upright. I am not sure of how long the rubber gasket would last if stored on it's side.

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 can definitely leave it and not worry about leaking. Screw the lid on properly though!

We try to always keep them upright, but we have never had issues with them leaking when on their side. I'm not sure if that goes for when they are on their side for an extended period of time

Yes it stays on well. I've turned it upside down and it doesn't leak. Just make sure it's on properly.

It can't if it mounting on out side. If mounting on in side will not work, because will not open and will leak very bad.

It is leak proof as long as you put the tab in the "lock" position, and have it assembled correctly. I throw mine in my backpack and the only time it leaked was when I forgot to lock it.

There is a pressure release on the ottom. No doesn't leak enough to merit giving it a bad review

Yes it does. I tested it out by holding it upside down and nothing leaked out.

Haven't tried liquids, but it has a good seal and if you don't tempt fate by storing it on its side, I don't think you will have leaks.

Yes it is perfectly leak proof. You don't have to worry about its pose in your bag.

Yes, very leak proof. I carry it in a bag all the time also throw on the seat of car. I own 2, neither have ever leaked when they are closed.

Yes at the base. The down side is there's a little side to side play with the spout. Not much. It troubled me when I first installed it but now I don't even notice it. I think I got a deal. No leaks

Mine does not leak at all, I think. Really like it and recommend. Easy to install
