I have used this for almost a year now. I find that it keeps drinks ice cold with only a few ice cubes for 3-5 hours depending on the outdoor temperature. I ride about 65 miles a day and this is amazing in the heat of summer. Water flows surprisingly quickly since the bottle is not squeezable (it's metal). The only negative is really the price-kind of pricy. I wash it in the dishwasher and lost the rubber ring inside the bottle that seals the lid. Fortunately, Bivo sells new rings for only $1 including postage.
These water bottles are clearly on the expensive side, but well worth the investment! I ride in the Phoenix AZ heat and it has always been a challenge to stay hydrated without drinking hot water or energy drink for the second half of the ride. These bottles keep the beverages cold! I have ridden for 4 hours in the heat and still have ice in my bottle at the end of the ride. I highly recommend this water bottle. If your water bottle cage is on the loose side they can rattle around and be pretty noisy, but on 2 of the three bikes I ride regularly they didn't make any noise at all. After I changed cages on the third bike to composite, tight cages the rattle stopped completely on my third bike. Now I don't hear any difference when I use these bottles.
I've bought various water bottles--plain and tepidly insulated--the latter lasting about twice as long as the plain one. Where I live we have microclimates, when I leave the house it can be 63' and eight miles inland 85'. This mean my ice filled insulated bottle water starting is fully melted at the 1/2 way point and will become rather yucky on the way back (and I still have another 500 feet of elevation to climb coming back. The Camelbak Podium is an excellent way to quench ones thirst on a hot day on my return leg, as it maintains the ice cold temps for two hours easily when kept full and makes the return so much more pleasant. It's a little heavier and rattles in my plastic water bottle cage, but a thin strip of Velcro dampens out the sound.
Many polymer bottles tend to get stiff as the temperature drops making for a harder squeeze made even more of a challenge with heavily gloved hands. Not these. This bottle remains flexible even in the very cold (0deg F).
I chose the white ones which seem to have picked up and retained some color from drink mixes I use. Better than the other way around, I would think.
We should probably use drink mixes without the dyes. I don't drink it for how it looks; who does?
