I recently ordered this product and was very thrilled with it. I had used gels for years and anyone who's used them knows how hard it is to open and eat while pedaling. Plus you have to bring large amounts of water because of how concentrated they normally are. This product eliminates all that. I usually bring 4 packs of gel for my longer (over 60 mi./ 100+km.) rides. It's very tough to carry that much water(about 64 oz./2 liters) if you don't want to use a Camelbak or other reservoir-type system and I don't. With e.f.s., I just mix one flask with some water or vegetable juice in my water bottle or drink it by itself on the fly and there's no problem. I don't get cramped up like I did if I didn't drink enough water while taking gels. I can drink it all for one powerful dose or sip it in steps. No sticky messy goo or lots of refuse to deal with. Great energy boost and lots of carbs, amino acids and 1500 mg. of electrolytes. No gel comes close. Doesn't taste bad either.

EFS is like rocket fuel when endurance training but it's definitely pricey. Was happy to find this vendor had it at a good cost and product came quickly.

The product itself is great but one of the bottles was not sealed properly so it leaked & I had to throw it out.
