Looks like an interesting product. Might be worth a try if they are being sampled during a major event ride.

Today I did an 80 mile ride in rolling terrain and in the heat. I packed one bottle of weak gatorade, one bottle of Nuun and took my hydration pack full of water. I also had a few trail mix bars and a stick of beef jerky as well as 1/2 a flask of hammer gel. At the half way point I reloaded and drank as much as I could, used up almost a full gallon of water for that stop - had to through out about a pint. I take Gatoraide powder and Nuun tablets to replenish the bottles. This has been working for me for a few seasons now - don't see any real reason to change.
