    Powerisers

        The ability to jump two meters in the air may not be something you have thought too much about. And most people have never considered running at 30 kilometers an hour. But just stop for a moment and think about how our new product could change your life.

        Your daily journey to your place of work is probably a mad dash for the bus. There is no point in taking your car because there are traffic jams, and anyway the car parks are probably very expensive or, worse still, full. Here is where Powerisers can help. It takes just a couple of minutes to put them on and then you are away, going past others or even jumping over the object which blocks your way.

        That is the practical use for our product, but then there is sport and exercise. Powerisers are set to be the next extreme sport and the deep-fit tools. You can imagine the 100 meters, the high jump or basketball performed by athletes wearing Powerisers. And what better way to build your muscles and keep fit?

        Our product is very simple. It is powered by a superlight spring, which uses the gravitational(重力的) pull from your body weight and pushes you with superhuman strength. There have been no records of serious injury related to the use of Powerisers, but extreme caution is recommended. We strongly advise the wearing of protective clothing, including at least a helmet(头盔).

        Powerisers make you feel as if you were walking on the moon. Now we make two different models: Basic and Professional. The Basic model is designed for the occasional users and costs around $ 500. The Professional model, which is designed for the competitive use, has a strongly-made structure and different springs, though that comes at the increased price of $800. Our Powerisers are guaranteed for two years and will be replaced without question if they fail during that period. That is how confident we are.
