8 reviews for Cirkul FitSip Strawberry Banana Flavor Cartridge, Drink Mix, 1- Pack

  1. Joanne


    My prouduct was delivered in 9 hours and I received it very good and the reason why I got the strawberry,banana sip is because I just got the new tumbler from cirkul and I forgot I had a gift card from Walmart so I bought it for my new cup shoutout to Walmart

    Delicious flavor, reminds me of jumex nectar
    My coworker informed me that when not in use to keep the dial off, unfortunately I didn’t know this until a day after I left it on so the flavor is a bit faded, but it’s still delicious. I love the banana flavor and the strawberry flavor in it isn’t acidic or feel overly artificial. I really like this flavor and I love that it has electrolytes added in.

    Pros and cons to the Cirkul Fitsip
    Super idea to get you to drink more water. You have to start at 3 level for flavor. Flavor goes pretty fast. Unique design I have to say. Young people should gravitate to your product. Older people will not want to suck on the water nozel to get their water.

    Great product
    Love the water bottle as it’s stainless steel and keeps water cold for a long time. They also have many great flavors to choose from. I drink a ton of water but get bored so it’s nice to have a huge selection. The only downside is, the flavor cartridges don’t last very long even when used on low.

    good way to spruce up your water
    my kids love these. they have several levels to choose the flavor intensity, but if they tip the water bottle or tumbler to far (such as taking a sideways drink while laying down) to get a drink it does spill out we have other water bottles and tumblers that don’t do it but it’s ok they love em still…. that’s my only complaint.

    Cirkul Is A Game Changer
    I love using Cirkul products to help ensure that I am getting my daily required levels of water intake. I hate drinking water by itself, but Cirkul sips have been a game-changer for me. This new strawberry banana flavor is delicious, it has the perfect balance of both flavors. I will definitely buy again.

    Purchased 4. One for myself and one for each of my 3 children. Definitely helps encourage water intake. Seeing it is flavored, they actually enjoy drinking their water. Being able to change flavors creates more variety. the mouthpiece being changed with every cartridge is a brilliant design. Flavors are perfect, and adjusting the amount of flavor you receive is easy with these cartridges.

    Tastes good
    I wish they weren’t 3$, but by the time you drink all the flavor out it was worth it. Your average drink at the store is around 3$ and you’re definitely getting more than one drink out of these. This flavor is good.
