Standouts
  • I love mine. I'm drinking water instead of soda or fruit punch, and it's cheaper than Propel.
  • The selection is massive — truly a flavor for everyone. Fast shipping and great customer service.
  • It's a decent product and the flavors are pretty good as long as you don't mind artificial sweeteners.
  • Great product especially if you are not a fan of plain water. Really helped me increase my daily water intake.
  • Keeps ice cold all day (11+ hours tested)
  • Clever 3-position FlowState lid
  • Dishwasher safe
  • Fits Tesla Model Y/3 cup holders
  • Lifetime warranty
Watch-outs
  • It's also a little noisy when you drink from the Cirkul Water Bottle. Not a huge deal killer but noticeable.
  • I am experiencing lack of flavor — I had to turn my cartridge to almost max to taste anything.
  • Leaks when tilted—can't safely go in bags
  • Dents and chips easily with normal drops
  • Heavy when full (~2 lbs)
  • Premium price for performance matched by $20–25 alternatives
