Firestar Energy Booster is described as a revolutionary sherbet confection that has been developed to provide long-lasting energy with none of the inconvenience of drinks.
The product is eaten like a sweet and the company behind the product, Firestar Energy Ltd, says it is seen as the ultimate energy shot.
The Firestar Energy Booster fits in a wallet or pocket.
Using patented technology to mask the taste of caffeine without using strong flavours, the company says the product relieves fatigue for four to six hours, outperforming most energy drinks and shots by around three hours.
Each box of 40 sachets weighs 130g, covers no more space than a CD, and retails for £60. Firestar is giving readers the chance to win boxes of Firestar Energy Booster. There are 10 prizes up for grabs.
