Fill your Cirkul bottle with drinking water and attach the lid.
Unwrap your flavor cartridge, insert it in the lid opening, and fasten it by turning clockwise into place.

Turn the dial to adjust the flavor strength.
Try starting out on a level 3 on the flavor dial.
Open the cap and rotate the flip cap to align with fin on the flavor dial. Press the cap down until the strap is locked onto the fin. This will keep the spout out of your way as you drink.

Now, tip up the bottle and drink! Want more flavor? Turn up the dial to a higher number. For less flavor, turn the dial to a lower number.
