Ultimately, it is just another Red Bull clone. It gains an extra originality point though for its packaging – still weighing in a 250ml, but in a much stouter can than normal, like a normal soft drink can but shorter instead of tall and thin. For 39p though you can’t really go far wrong, and it tasted very nice with none of the usual bitterness or sour aftertaste associated with cheap energy drinks.
UPDATE: A bit of research on this product has shown that it may actually pre-date Red Bull, and therefore be more original than originally thought (?!) Check out its mention on Wikipedia.
