Can you shake with the lid on without leaking?

No. It will leak when shaken but if left upright for transporting it will not leak.
2009265
No. The pour spout in the glass will allow liquid to flow out even with the lid turned away from the spout.
2009266
No. The lid does not seal, it is loose. My one complaint. Otherwise they are nice.

Absolutely Not, these lid are no were near that tight. They are better than nothing. If I need to shake them or turn them upside down I use other lids from other bottles.
2009268
Absolutely NOT. It doesn't make any difference what position you hold the bottle, if you shake it the liquid goes everywhere because the lid is terrible and doesn't fit tightly.

Absolutely not! The lid does not seal at all. They have a better version that closes tighter w/a rubber or silicone type seal. But, on this one, the lid just sits loosely on top.

I agree the lid appears loose. However, I've had nothing spill or even leak during traveling.

The lid snaps down and should not leak. (Haven't tried it, though a bucket with guck in it shouldn't tip over.)

Definitely clicks when you put on the lid. Then the lid is somewhat loose while on. It would not come off if you shook it, it requires a little force to remove the lid. The lid is not airtight.

No lid. It's a non-spill for the most part unless it's really shaken upside down, and even then, it's only a drop or two.

Sorry, nope - it will leak if you shake it and it's full enough to collide with the lid area

I haven't tried that yet, but if you seal the lid on tightly (and there is a trick to doing that) I suspect it will not leak. I suspect the biggest problem will be when the plastic lid starts wearing out and becoming more brittle. Then it may start leaking.

It is hard to tell when the lid is on right. I would cover it with a towel before shaking.

We haven't had any leaking. But in the tipsy hands of my two year old it will spill out the top if the lid is off. :) we enjoy them outside!

They don't have screw tops. I am not sure if they would leak. You can twist the cover so they won't pour. I have never tried shaking them, but I think they would be okay.

No rattling. There is a spring hinge on the bottom of the lid. The straw holds it open and it holds the straw in place.

Mine does. I think I must be the only one. It doesn't rattle but water collects in a little hole under the lid handle. Every time I clean it, I have to unscrew the handle to remove the water. I had to order a replacement lid. Hope this one is not defective.

yeah if you shake them up side down they will leak but my kids dont shake there cups upside down so i didnt see that as an issue for me. but any sippy cup will do that. there really is no such thing as a 100 percent free leak cup i wish there was.

Not when I open it. When I fill the box and then secure the lid it spills over a little.

Your question got me thinking, so I did a quick test. I filled one up with a bit of water, put the lid in place and tried 1) holding it upside down and 2) jostling and shaking it. The results: I did not see or experience any leakage. Hope this info helps you out!

As long as the lid is on all the way and the flip top is snapped down, there is no leakage.

no.. just a "thermos styled" shaker... there is a valve in the top that you can close or open and the lid screws on/off... measure/? who measures?? haha... long live the "free pour"...
