Like the taste, used this on a Gran Fondo and it worked. While I used the refuel stops to fill water bottles I didn't need to get food. Spent less time at the restrefuel stops more time on bike, finished faster.
Stuff works, 'nuff said...but...
At $1serving (the regular price), I don't find particular value in buying bulk. A GU competitor sells their bulk bottles at $0.77serving. The premium GU Roctane is $1.66serving. That MSRP is too steep for me.
Love the taste and very easy on my stomach. I have seen numerous comments about the flask and related on-bike storage but do not see 6 individual packets that each leak and make a royal mess after opening as being a better system. I do not want 6 opened, sticky packets in my jersey pockets. The problem is that gel is inherently messy and incredibly sticky - you cannot 100% empty it from any container. Personally, I would rather have a single large flask than repeatedly tear off the little opening tabs at risk of squeezing while doing that and covering myself with gel. And it is just not that hard to put a flask in a pot of hot water to clean it.
