Why is this Blue one not for use with hot liquids?

There is a plastic straw and insert inside that is not meant to interact with hot liquids

The color is dependant on the temperature.blue when it's cool water, purple for warm (my preference), red for hot and flashing red indicates the water is dangerously hot

The instructions say not to use it with very hot liquids. You might be able to do it but it may not last as long.

Tina,Thanks for asking, a bit surprised you'd ask me as my review was a rather strange one to say the least. It says very plainly NOT to use with hot liquids, but also says 'dish washer safe '??? My dish washer gets pretty hot, especially if I use the dryer (which I usually don't) but have had no trouble with that. With that warning, I've never used one for coffee, but with a dozen of them and just 1 of me, I'll try it out. I see in other comments that they have been using them for coffee with no trouble. What the hell, take a chance. FINS UP! Robbie

Yes you can put hot liquids in it. I use mine for home brewing and often use it for sparge water at 170F

No. If you got to life factory website it states it is not meant for hot beverages

Like Chris said, the bottle instructions specifically say *not* to use hot beverages in it. While I'm sure the bottle is *able* to contain hot beverages without melting or spontaneously combusting or anything dramatic, even BPA-free plastics leach chemicals, and the effect is worsened by excessive heat. http://www.npr.org/2011/03/02/134196209/study-most-plastics-leach-hormone-like-chemicals

The blue button is for cold frothing. I find that if I froth and leave it for 30 seconds then it's frothier

I would not drink a hot beverage directly from the stainless version. There is a silicone version (http://amzn.com/B00FP6JFNM) that is a much better solution for hot drinks.

I had the same concern - couldn't figure out why the thing didn't work as a traditional "commuter" mug. It isn't. Think old-school thermos. Unscrew the top and drink or pour. And be careful if driving - the liquid stays hot.

I don't know about keeping it hot. I haven't used it for hot stuff...just cold. Sorry!

It's not for hot beverages, only cold. It either says that on the insert flyer or on the bottle.

I haven't used it with hot liquids yet but the mug gets super cold with ice. I think just like any other cup this will get hot with hot liquids but the handle doesn't seem to be effected. I would try hot liquids in it myself personally.

I would think something would have to be heated to the extreme before it could cause damage like melting. I have hot coffee on mine everyday and have no problems.

Yes it can be used in hot liquid. The part that goes into the liquid is stainless steel just like the corded ones.

It would probably get too hot to safely handle- it is really for water or juice

I've never used them for hot liquids, but I am pretty sure you can . They are used for canning preserves, and they are usually hot when they are put in the jars.
