- Fission Caffeine Flavor Water Variety Pack, Makes 36 Drinks, No Sugar, Zero Calorie Drink Mix, (2 Send It, 2 Jackpot, 2 Blue Magic)

The GoSip was a winner with me and my husband! The blue raspberry is my favorite and his the black cherry! We both really enjoy the strawberry watermelon!! A big winner in our eyes 😁 it lasts a good while And the caffeine content isn't too heavy! Def worth the price for 6 of them! Easy to use And the variety is great!

I bought this for my son. He got a cirkul for Christmas and needed replacement cartridges. This pack is a much better value than buying individually at the store. All 3 flavors taste great and he loves that you can customize the strength of the drink.

I made the mistake and got these for my grandson. He does not need caffeine. I should’ve never bought him these, but he loved the flavor. But too much caffeine made his stomach hurt. It’s my fault. I should’ve paid more attention to what I was buying. But I give these five stars because they do love them.

These flavors are just ok. The black Cherry kind of tastes like cough syrup. The other 2 were good, but had a bit of a weird aftertaste.

The Cirkul GoSip Caffeine Flavor Water Variety Pack is basically the adult version of discovering cheat codes. It’s water… but with energy. Hydration and motivation in one sip? Sign me up. Each flavor is like a little personality test — am I feeling like “Citrus Blast CEO” today or “Raspberry Energy Gremlin”? Either way, I’m sipping my way through the day like a hydrated superhero who definitely has their life together (even if I don’t).

The flavors in this pack hold up more than 24 hours. Compared to other flavor packs I've tried, the flavors hold up more than 24 hours whereas other packs' flavors are depleted by the end of the day. I haven't noticed any significant energy effects so I can't speak on that.

These flavors are good you got to try them!

The idea behind this flavor cartridge system is great, and the variety pack offers a nice selection of flavors to try. The taste is generally good when the cartridges are working properly, and being able to adjust flavor strength is a nice feature. However, it is not as convenient as I thought it would be. The cartridges often seem to stop dispensing flavor even though there is still liquid inside, which feels wasteful. I have tried adjusting them and cleaning the connection points, but the issue still happens. For casual use it can still be enjoyable, but for the price I expected a more consistent performance from each flavor pack. If the manufacturer can fix the dispensing problem, it would be a much better product overall.
