My daughter and I recently discovered Holy, and I’m completely satisfied (I’m 60 years old). For those who criticize the price, consider this: 2 doses of Holy make 1 liter of drink, which means 25 liters per box.

At 40 euros a case, that comes out to 1.60 euros per liter. It's no more expensive than a standard soda. Dominique Thiery on Trustpilot.
