I'm on the bench with these drinks. I love that they mix in with water and aren't fizzy, but I think they have an unusual after taste I can't put my finger on. Kinda herby like something savoury. I got the starter energy ones, some are better than others as you'd imagine. The starter pack is great for trying them. They're drinkable for sure. Will get through the last couple of flavours and decide to order again or not. Overall they're alright though and great alternative to the fizzy, sugary drinks.. Also, delivery was mega fast considering we're in Scotland.
