Question: how many hours does cold water last?
Document: I love this water bottle, it gives water a great taste, and Ive gotten many comments on how people like it. Im considering buying other colors its just that cool. Its also can be attatched via caibener to any bag on strap, very functional
I've owned many water bottles and this is by far the best. The top removes quickly with half a turn and seals amazingly well. It's comfortable in the hand and the opening is the perfect size to gulp water without worrying about the water spilling out around your mouth. The rim of the vessel has a smooth finish with no threads. I'm surprised at how comfortable it is.
I always carry a reusable water bottle, and I thought these waterbottles looked sleek and cool. (Plus Oprah endorsed them.) They aren't practical for me. They do not fit into many of the various holders I use - namely in my car and on my elliptical machine. Which meant I couldn't drive safely and drink water at the same time. Then I put one in my purse and it leeked all over.
beautiful bottle, i was REALLY happy with the delta but since I am a heavy duty bottle drinker and on the go i dropped it many times and the plastic hinge broke due to my abuse. I opted for the stainless steel vida.
I'm happy that the water bottle is BPA free but I wish that it was USA made.
this thing sucks so bad, i had high hopes for it but it leaks water out all the freaking time. I'm about to toss it in the garbage.
This was the perfect bottle for me. The mouth isn't too wide so water doesn't spill when drinking, it hold the right amount of water for me without being too heavy and, lets face it, it's super stylish!
The best part is the plastic lip on the bottle. No more weird steel taste like I got from my Sigg bottle. I am finally done water bottle shopping!
Good looking bottle. Hasn't leaked so far. No problems with outlook. Smells heavily like 'chlorine' (or metal) when you leave water too long in, so need to replace quite often.
This was a gift for my son who is at college quenching both his thirst for knowledge and fresh water. The KOR Vida allows him to do this in a way that is both good for the environment and incredibly stylish. Plus, he says the girls love it!
