For the good points, yes, it definitely tastes like Wintermelon. No issue there. It's also good for lactose-intolerant people. You could also tell they used stevia. The sweetness isn't candy-like and sharp which is why I was sure it was stevia. And, I definitely felt the appetite suppression in the next 10 minutes. I nearly skipped out dinner because I accidentally drank it an hour before dinner. The appetite suppression lasted up to an hour.
But I wouldn't have bought it without 1) it being 60...
