I can definitely gush about this brand. I had to do my internet research for a well formulated smart energy drink. I had liked Celsius drinks, but those have issues: it's not feasible to stop drinking half a slim can to keep the caffeine level moderated. I replaced those with these awesome Cloud Water energy drinks. The 90 mg of caffeine is that 1 cup of coffee: PERFECT. What's even better is no artificial sweetners & not much sugar but it still has a great flavor. Healthy, tasty, and I don't get anxiety from overdosing on caffeine. It checks all my boxes. Every cold can is my tasty treat that doubles as my liquid energy with a healthy Rx dose of caffeine. On top of that, when they accidentally shipped me the wrong flavor, I only had to send 1 email and they were super customer friendly about making it right without hesitation. They shipped a replacement case with a day. Great product & company.
