“I bought the air up bottle and am still liking it.
The taste is mild and very weird at first. Your tongue can tell it's plain water, but you still get some "taste" when you swallow and the air goes up your nose. I have always liked mild juices and usually add water to normal juice, so I like the "taste" the air up produces.
Also drinking from it takes little bit to get used to, but my dumb a** got used to it quickly and I'm sure you will too.
About the bottle. I was returning home from my friends and had the bottle on a side pocket of the backpack, so I fling the backpack to my shoulder and hear a loud clang... That was the sound of my air up bottle hitting the asphalt. I noticed that it was leaking and the plastic between the cap and the metal bottle had jumped from its thread. I got back to my apartment and feared the worse... But when I took it apart I noticed that there were no cracks, holes or anything that would make it unusable. I filled the bottle with water and screwed the middle plastic back, turned the bottle upside-down and nothing leaked. I was so relieved.
I can say after that experience that the bottle is made of quality materials. There's small dents and scratches on the bottom and on the side of the bottle, but the bottle still works well and it keeps my water cold for a long time still.
I full heartedly recommend this to people who don't want to drink plain water and want it to have a small taste. But don't expect strong flavour. Some flavours are stronger than others and you have to test what you like the best. Also, if you dont like the flavours you can use this as a normal waterbottle.
As a last note. Air up bottle has increased my water drinking and that's a really good thing.”
