I was only able to use the bottle a few times when it was hot. I put the same number of cubes in this bottle and my regular Camelbak Podium. I used the Podium first and it was out of ice before the bottle was gone. When I switched to the Podium Ice still had a few pieces of ice left. Water was still cool but ice was gone shortly thereafter. The other time I filled the bottle to the top with ice and there was quite a bit left when I started using the bottle. I think if you freeze it half full with water it should do even better. I still need to do more tests before I would give it 5 stars, but I expected more given the price.
So, I live in a forest with a mile of gravel road to get to asphalt. That led me to get a gravel bike (bike number 8). Then I needed a water bottle cage - my gravelly was a lightweight Specialized Diverge - in black - and the Blackburn Bottle cage was PERFECT! It works like a champ. I have used Blackburn products in the past with little to no disappointment, where they have exceeded expectations and this bottle cage is no exception!
