Review: good energy packet - Great product! I use it for longer than 2 hour bike workouts. I like that is not too sweet, but sweet enough to make me like it...'mildly sweet's is especially what I like after 3 hours in heat. And it's easy to digest and gives me energy on the bike.
Review: These Are Great - I'm not sure why this is getting some bad reviews. Do people not know what a gel is supposed to taste like or what the typical consistency of a gel is like? It's perfectly fine. Actually the tropical flavor is pretty darn good compared to some others I've tried on the past. If you're an athlete who participates in endurance sports, then you know what to expect from an energy gel. This one is really no different. Skip past the negative reviews. These work exactly like they're supposed to and taste good. The consistency is normal, a tiny bit less bulky than some of the other gels out on the market but, in my opinion, that's a good thing. It also gets to work quickly, which is another positive when your tank is almost on "E." One thing I will say, I found it a little tricky to get the last few drops out of the packaging. These don't seem to be as easy as some of the other energy gels you can simply squeeze from the bottom. I had to stop during my ride and use both hands to get the last bit out. I have small hands so maybe that's part of the issue. Very minor detail and not a deal breaker, imo.

### ⭐⭐⭐⭐ You'll have to carry a backpack full of these for long events.
*by T***E on May 25, 2018*

Having used almost every energy gel product out there, I was anxious to try SiS Energy Gel over the course of a few 2 hour + training rides that I was putting in for some upcoming endurance events (I always try new products in training settings before trusting them enough for a race). I found the taste of the lemon & lime to be neither lemon nor lime, sort of a bland citrus like flavor, which wasn't horrible, it just didn't wow me. To be fair, most energy gels don't taste all that great anyway. The consistency is true to how they describe it, more of a liquid rather than a gel, so it actually empties out of the sachet rather than having to squeeze it out, like with other brands. This makes it a little easier to actually get in the mouth rather than all over your hands (and gloves, and shift levers, etc). The main thing I do not like is the low calorie count, about 80 calories per sachet. For a 3 or 4 hour event, I would need to stuff my pockets with these if I were going to rely on them as my main energy source. I am looking forward to trying some of the other flavors, especially the ones that have caffeine.
