I drink C4 energy drinks regularly and have never had any problems with them. They taste great, arrived in good condition, and I’m happy with my purchase

Had to change my selections to flaveors that were in actually stock for the subscription, then when they arrived 2 of the cans were broken open. Love the product when I can get the flavors I want and intact.
