You thought the consoomer thread was the best place to ask lol?
I have a personal vendetta against subscription-based water bottle flavorer cartridges. Only can be used in their special water bottle. Is "mailed straight to your door!!!!" really still a selling point in the age of grocery delivery and amazon? My family buys them because "they will help you lose weight." The water in the bottle stays clear, it's flavored by going through the proprietary flavor cartridge. They think this is healthier than other ways to flavor water because they still see just normal water rather than seeing, like, how crystal light and other 0 cal things typically have a bit of food dye. I don't know. All I know is a subscription service water bottle drives me insane.
