Bigbang Hi Stick is an energy drink launched by COFCO Womai in collaboration with Refresco, the largest independent bottler in Europe and North America, with 0.75mg of guarana extract per bottle as the main refreshing ingredient. Guarana contains caffeine, theophylline, and theobromine, which contains 4-6 times more caffeine than coffee beans. However, the caffeine content is not directly marked from the hi bar, and from the feedback of drinkers, the refreshing effect is acceptable.
 
While the caffeine content is not labelled as biased, Hi Bar is superior in taste to many energy drinks. The black can is a classic original flavor, the same as other energy drinks, and also has a strong Red Bull color, but the sweetness is slightly lower than that of Red Bull, with a slightly bitter aftertaste and a more murderous taste with bubbles. The lime mint flavoured green can has the highest rating, with a minty aroma that hits the nose and a mojito-like coolness, comparable to Monster's Ultra series. It's a pity that although the main sugar-free silver can has lower calories, it is not obvious that it is sweet and sour, and the taste is mediocre.
 
Hi Bang is currently sold on COFCO womai and Tmall, and the price fluctuates greatly, with a minimum of 3 yuan/can, and usually more than 6 yuan/can. However, it may be that due to the fact that the offline channel has not yet been opened, the shelf life of the product is usually embarrassing when consumers buy it, and most of them are produced nearly a year ago, or the expiration date of the product. Consumers are advised not to stock up on goods when purchasing, so as not to be careless and put them before they expire.
