Cirkul Puressence Unsweetened Flavor Water Variety Pack, Makes 36 Drinks, No Sugar, Zero Calorie Drink Mix, (2 Cucumber, 2 Peach, 2 Lemon)

**** The Cirkul flavor cartridges marketed as unsweetened have garnered a mixed reception from customers. Many users appreciate the product for its innovative mechanism that allows for customizable flavor strength, making hydration more enjoyable without the addition of calories or artificial sweeteners. The convenience of changing cartridges is also highlighted as a positive feature; swapping out flavors is a quick process that requires minimal effort. However, the actual performance of the flavors has led to significant disappointment. Users describe the flavor intensity as weak, likening it to merely infusing a cucumber slice in water, which does not provide a strong representation of the intended fruits or vegetables. While the cucumber flavor has received some praise for its authentic taste and longevity, other options, such as lemon and peach, have fallen short. In particular, the lemon flavor has been compared unfavorably to cleaning products and left many users unsatisfied. Many reviewers also expressed concern over the longevity of the cartridges, stating that they may only last for a couple of fills at maximum strength, creating a feeling of wastefulness with each disposal. Overall, while the idea behind Cirkul and its unsweetened cartridges is welcomed by some for encouraging water Consumption, the execution in flavor remains a contentious point. Users are left wishing for more vibrant options to justify the cartridge costs. **
