Can we put very hot water in the bottle? Can this break the sealing rubber in the lid?

You can put hot water and won't damange the pouring plastic. BUT outter casing will be the same temperature as to water temp, you will get burned if not careful. It is not temp control bottle.

I think you could make it work that way but if its a hot liquid you will likely burn yourself since they retain heat so well. Best bottle I've ever owned!

No not in a bottle warmer you put hot water in a cup or heated water and place the bottle inside that for 2 minutes or depending how warm the water is because if it's in hot water it'll get hot fast.

Yes, the seal is very thin and will not compress when the lid is screwed on. It is a novelty item only. I think it would be the luck of the draw if you got one that didn't leak.

It won't do the work of a Thermos. I would be most doubtful that this bottle is a good one in which to carry water that is boiling hot. I carry a canteen cup for the really hot water. And I carry my Nalgene for the best drinking water and as a source of excellent water to boil for coffee, tea, freeze dried food, etc.

Don't freeze your bottle! I put in 14Oz of water and mine exploded. Don't freeze your bottle. It will break.

I would not recommend using it to hold hot water. Only use lukewarm at best. Keep in mind the cap is not airtight, so whatever steam it couldn't hold will put pressure on the cap's seal and lid, and might end up leaking between the walls. I have only used this bottle with lukewarm liquid and that worked OK. I also experimented with carbonated drinks and that resulted in a bit of leaking from the cap. I forgot if the seals leaked, but I definitely got the fizzy liquid on my hands when I opened the cap lid. Now imagine that being trapped hot steam/liquid. I don't think you would want to have that.

I use these bottles for hot tea all the time and have never had any problems. In the few years that I have owned these bottles, I have only ever lost one when I accidentally left the bottle full of water in the car overnight during an extremely cold winter night. I think that as long as you avoid extreme temperature changes you will be fine. You can always run the bottle under warm water first to warm it up. Also I never pour boiling water directly into the glass, but wait a minute or two.

If a water bottle has a lid and does not leak there must be a soft seal. (To the best of my knowledge anyway.) I don't think it is possible to have a water bottle that never comes in contact with any plastic or rubber with a lid that seals.

I have been trying the bottles for hot tea. So far, two have fallen apart. The first bottle was working fine but the steam eventually loosen up the lid. One day, the bottle fell off from the lid and shattered on the floor after 1 year of use. The second one just broke today (bought in Sep 2014 -> less than half a year) when I was pouring hot water for my tea bag. The hot water broke the glass and the hot water split and covered the entire cabinets. I will not buy this again for hot tea but would consider for other purposes.

Yeah, locking mechanism breaks if you drop it on the lid. You can purchase replacement lids and the plastic bottle itself is solid.

I would advise not to put in microwave or even put hot liquids or carbonated drinks as well. Only put water or other cool liquids to prevent damage to the bottle.

Yes you totally could and it is thick enough to do so, there is no rubber O ring, someone said there was, there's a plastic insert in the top of the lid that seals it, I know this because I still own and use mine, you could boil water in it but would need to remove the lid while doing it and use foil as a lid for increased boil speed, keep in mind the flask is so small boiling water in it would not be practical for drinking purposes, it's great for storing emergency fire starting fuel though!

I honestly don't know. The only thing I have put in mine so far is water, but I don't know how it would hurt it either. I would think I'd you use the original lid it comes with it should be just fine. As far as I can tell its just like a thermos on the inside. Hope it helps!

Not at all. I've had this mug for about 4 months now, and it's been nothing but absolutely great. If you put hot stuff in there, you can expect it to stay hot, without affecting the temperature of the outside of the bottle. In fact, you can just consider the outside of the bottle to be almost completely isolated from the inside, as the isolation is done extremely well.

If you remove the strap it would not be a problem. I'm not sure why Sara thinks it being thin is an issue, you can boil water over a fire in a paper cup. As long as it has water in it, the metal can't get over 212 degrees F. Also the water will prevent part of it from getting hot much faster than the rest of it. At that low of a temperature there is no chance the bottle will warp no mater how thin it is. Just be sure it is completely full and the cap is off.
