Positive Reviews:

This drink has a higher salt content than other drinks that you can really taste. The first time I drank it I was unsure about this product. After using cytomax for so many years any change was going to feel strange. The next day I used it I was ready for the saltyness and loved it. On a hot summer day you can feel the electrolytes being replaced .I have only used the lemon and lime flavor, but now it is my favorite drink out there. Unfortunately it is twice the price of cytomax so I only use it on 3+ hour rides.

When I'm on the bike in the summertime I sweat like a (insert crude joke here). The amount of electrolytes in EFS keep me from cramping up on long rides while I'm losing all the fluid in my body. A year or so ago they changed the formula & the lemon lime which used to be my favorite flavor became a bit too tart for my liking. After trying the Fruit Punch (too sweet) I've settled on the Orange as my new drink of choice.

I'm a big fan of First Endurance products. The energy and endurance drink is key for long rides, replacing electrolytes. I have been on rides where my friends are bonking on climbs and I'm still motoring on. I partially attribute this to staying hydrated with a product that is designed to keep your motor running. The flavors are pretty good. I'm partial to the fruit punch and grape flavors but I'm not a huge fan of the lemon-lime.

I usually don't like drink mix and prefer water. But now that the team is using this mix, I have slowly shifted from racing with all water to all EFS mix. It tastes good and doesn't require water to wash it down. It also delivers a few calories per bottle so I can eat one or two less gels per hour when racing.

I love this stuff, i was previously using carboroket but i like the stronger taste of this better than the very subtle taste of other drinks like carboroket or hammer, but then again my stomach handles about anything.
keeps my legs feeling good while riding and I dont ever gets cramps after

When it comes to these types of drinks I've tried them all, to find the best one for me. EFS I think is spot on, with their product. Works well, I tend to feel a little more endurance and I don't cramp as much.

First Endurance make great products. I like their range of flavours in drink mixes. I honestly think this helps me stay better hydrated in races, and it contains some very helpful nutritional products like glutamine too.

The stuff really does work. I have been taking the lime one and i don't think there is much of a taste. Add some liquid shot in the drink, and BAM... your away.

This stuff is solid as an electrolyte replacement. I'm partial to lemon/lime flavors and this one is pretty good. Not as sweet tasting as OG Gatorade.

Helps me avoid cramps. Pretty salty, wife can't stand it. Bland and I like that.

Negative Reviews:

The lemon-lime tastes pretty gross, but it's the only one I've had so I don't know how the other flavors are. It doesn't have the carbs and calories of CarboRocket (which I'm going to stick with) so you definitely have to supplement with bars, gels, or whatever. I'm sure its electrolyte are great, but the taste is pretty nasty, especially when it warmed up on a hot ride.

Neutral Reviews:

I like the tast of the EFS mix. With higher temperatures I combine it with 1 bottle of water to avoid stumach problems. But in Holland I would just race and train with the First Endurance Drink Mix.
