I didn’t buy this on Amazon, but the Cirkul water bottles are awesome. Cheaper overall than buying energy drinks, but much better for you, easier to swap out flavors, practically never have to wash them by design, and it keeps me way more hydrated.
Bought mine from Walmart for $20, each drink pod lasts me 3 days at $4/pod, meaning I spend about $9.33/week on average, assuming I drink as much as I do consistently. The energy drinks I like most are about $2.50/each, so that ends up with $17.5/week, and that still means I have to throw it away and find another drink for the rest of the day. This one I just refill with water.
Since the flavor strength can be adjusted with a dial, it suits pretty much anyone, and because turning the dial to 0 means just water, I can easily just switch to plain. Definitely worth the investment.
