## Customer Reviews

### ⭐⭐⭐⭐⭐ Works well
*by K***N on February 9, 2024*

Great for long run fueling. I make my own energy gel using chia seeds, the seeds get stuck unless I crank the lid as open as it goes, which distracts me enough whilst running that my pace slows. I don't like that, so I think next time I will try grinding up the chias. It would work perfectly with Gu though, since obviously that's what it's made for. It doesn't leak gel, but I think it would probably leak water. It's the perfect size to fit in my FlipBelt, it's pretty easy to clean, and it didn't come with any funky smells or anything. I'm happy with it, and will likely order another so I can carry 2 with me for my first full marathon this fall (I'm slow, so it'll be a long one.)

### ⭐⭐⭐⭐⭐ Good but individual Gu are easier
*by J***  on May 28, 2024*

Great sturdy product everything works great and holds up on long hikes. Refilling can be kind of a pain also if you like different flavors lie I do this probably wouldn’t be the best choice because it holds more than one serving of gu so you would have to purchase multiple. A great positive though with sticking with one flavor is that you reduce trash you have to carry with you.

### ⭐⭐⭐⭐ Works great!
*by E***K on May 14, 2017*

It works great, not sure what all the negative response is all about. I like that I don't have to deal with empty pouches. I have no problems filling it or using it. I found it to be less messy than pouches. I do not have any problems opening it, it only requires on hand and my teeth are fine. To clean, I recommend soaking it in warm water just to dissolve any gel still in the pouch. It is far and away better than individual pouches. Gave 4 stars because I think its a little over priced.
