Overview

Not a bottled drink, this is a pack of flavor cartridges used with Cirkul's Flavor Dial technology, which lets you set how strong the flavor is. The title adds that it carries caffeine and has no sugar or calories.

The strength dial and the amount of flavor per cartridge are what set it apart from a premixed bottle. The listing leaves out the flavor, the caffeine amount and which bottle the cartridges fit.

Who it's for

Water drinkers who like to change flavor strength during the day and want a caffeine option. Those watching caffeine, or without a Cirkul bottle, should confirm details first because the listing gives neither.

Pros and cons

Pros
  • Adjustable flavor strength
  • Zero calories and no sugar
  • No artificial flavors or colors
  • Many bottles' worth per cartridge
Cons
  • Caffeine amount not listed
  • Flavor not named
  • Needs a compatible bottle

Performance notes

Flavor strength follows the dial setting, and the listing notes that the amount of drink per cartridge varies with that setting. A lower setting stretches each cartridge across more water.
