Does this insert just snap into the Nalgene lid? Is the bottle's original lid able to screw down? Does this insert shift out when when drinking?

Nope, its pretty snug when you place it in, but also easy to remove with your fingers. The lid is externally threaded and this sits in the inside, so the lid is able to screw down all the way with no issues. I hope this helps!

Sorry for the late reply, basically what everyone else said... Slides down into the mouth of the bottle, fits snugly so it doesn't shift easy, cap can still screw closed.

Yes, you just slide it in. It's silicone, I think, so it's flexible but it's also firm with enough surface friction to not move once in place. It's easily removable but does not shift about unless you want to move it.

It doesn't really snap in, it just kinds of slides into the opening. The lid screws down fine and doesn't leak or anything so that aspect of the bottle is unaffected. I've never had it fall out or in while drinking. I've had them for a while now and they are just as good as day one, I've run them through the dishwasher multiple times a week. They recently started to have an aroma but a quick boil took care of that. All in all it's a great product and I highly recommend these splash guards!EDIT: I have left my bottles rolling around the floorboard of my truck and never had a spill.

No the insert fits down into the top of the bottle. The lid is able to screw down tightly. The insert stays in place when you are drinking out of the bottle. It is nice as it makes the opening smaller so you don't get water all over you when you are drinking if you happen to hit a bump while driving!

The insert is a flexible rubber so it fits inside the neck of the bottle. The original lid still fits as usual. The insert does not shift when drinking but it can be pushed to far in and then it will drop down into the bottle.

It fits snugly into the inside of any Nalgene bottle that has a standard-sized opening, and sits flush with the top. The lid will still fit on the outside of the bottle perfectly. Because it is made of a flexible rubber, and fits in snugly, it won't come out until you pull it out using the slight lip at the back of the topper.

It seems to snap in to the cap very securely. I haven't had any issues with that.

Tight-fitting lid = -0- access and -0- breeding....just make sure it is well-sealed. Ours certainly is a tight fit and no accidental shift possible if you've put it on per manufacturer's instructions.

The clear plastic insert attached to the bottle is supposed to fit inside the bottle lid. I have two bottles and when lid is screwed on there is no leakage on either one. I wonder if there is a defect with the clear plastic insert or the lid. You might check to see if the clear plastic is inserted rightly into the bottle. I have tested mine a few times after reading this, and mine are both sealed tight when lid is screwed on. You might contact seller. I am very pleased with my product.

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.

I was able to squeeze the Momma nipple in my Nuk orthodontic bottle ring, but it wasn't a "proper" fit so I would say don't do it. It fits in my Avent Classic and my Dr. Brown wide neck bottles... but Dr Brown's say you aren't really supposed to swap out parts because of their special vent system. So I am thinking it was probably not a good idea.

My 18 oz. came with this type of flip lid. I just bought a 32 oz flask and put the flip lid on it but it doesn't have a complete seal so it leaks when I shake it or drinking from it. I've tried to re-adjust but it just will not twist down completely. So I bought the flip straw lid which does work. That said, my brother has this flip lid on his 40 oz which strangely fits on my 32 oz. No idea why one fits and the other does because they look exactly alike!

Yes, the top does screw on tightly, but I haven't turned it upside down to check for leaks. And anyways, the lid needs to be loosened up a bit so that air can get into it, so that the liquid flows out easily. The spigot did leak a little at first, but stopped after I tightened it down a bit. It has worked great ever since. We like it very much! Hope this helps.

It is a plastic insert. You can see the black plastic on top that is part of the insert in the picture. The lid screws on. My only complaint is the gasket on one of these I have did not last long, and I see no way to get a new gasket for the lid.

The lid does not screw on or snap on. It's like a rubber seal that adheres to the top of the mug when you push it down. And YES, there is a straw hole. The tab you can see in the picture covers the hole when/if you prefer not to have a straw in it. BTW, I suggest getting extra long re-usable straws, like they sell at Bed, Bath, and Beyond for tall Tervis tumblers. Standard straws are just not long enough for this mug.

Yes, it unscrews. I LOVE this thermos! I have five of them. I reserve two for coffee, because there's a slight coffee smell if I try to put water in after the coffee.

The bottle is special and snaps into the ring on top very snugly. My two complaints: Too Small. Cannot remove the bottle ring for cleaning. No leakage or overflow problems so far.

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.

It's not the blender lid, it flips open and has a little hole to drink from. It hasn't ever leaked but then again I've never been very rough with it. It closes by pressing the lid down, so it's not hard to work.

No, the pop-off lid and the plastic insert are part of what makes up the screw-off top. You screw off (sorry for the redundancy) the entire top to drink. Hopefully that explains it.

It unscrews. If the top is stuck, gently use the part on top that closes the opening that you drink from and turn it to the left. After filling "Bubba" I always make sure to wipe the threads on it dry.

Yes. It comes off very easy and snaps back in. I like that if fits in without having to mess with a lid.
