Innovative Gyroscopic Resistance Training makes it easy and fun to exercise Anywhere Wrist movementView larger The innovative exercise machine will allow you to exercise and work-out ANYWHERE! Don't let the small size fool you. Pick one up, spin it up to 10,000+ RPM and you'll be amazed by the amount of physical work required to keep it spinning at speed, using such a small compact motion. Go ahead, feel the burning forearm after a minute of use. Because the resistance is provided by angular momentum built up through a spinning mass, a few minutes a day on our Spinner can be equivalent to hours of full motion work with a dumbbell or a curl. For athletes, amateur and professional alike, strong grip and forearm provide the ultimate in power, speed, and control in just about everything you do. Be it golf, tennis, baseball or just about any sport that involves the use of hands and arms, using the NSD Spinner will allow you to hit it harder, hit it faster and hit it straighter. Besides the physical benefits, it is just downright FUN to play with. Challenge a friend. Challenge a co-worker. Or a family member. See who can make the Spinner spin faster or glow brighter. See who can keep their Spinner spinning longer. Or break it out during "break time" at work as your co-workers gather to watch in awe. You can have fun while exercising, or exercise while you have fun. Tips on Operating your NSD Spinner No battery required; Just like riding a bike! Your hand is the battery of this device. The motion of your hand rotating the Spinner is similar to making ice cubes swirl inside a glass. The essence of operating the Spinner is not about how fast you rotate your wrist. It’s about how to synchronize your wrist rotation to the momentum and timing the rhythm of the rotor’s gyration. The faster the rotor spins, the easier it is to operate. Make sure you start the Spinner with sufficient speed. Maintenance *Keep your Spinner from dusty environments. Don’t put your Spinner on the carpet or any fabrics. Dust may be brought into the internal surface of the shell by the rotor and make the inner tracks dirty. Eventually it would make noise as the rotor spins. *Wash your hands before using the Spinner. Sweat or lotion on your hands will decrease the capability of speeding up the Spinner's RPM. The Speed is increased by the friction between the spinning rotor and the inner tracks. Never lubricate your Spinner. Oil is the killer of its friction. *Clean your Spinner periodically. To clean the Spinner, take off the rubber band, unscrew the shells with a precision screwdriver, insert a coin into the gap between the upper and lower shells and then twist the coin to open the shells. Once you disassemble the Spinner, (remove the digital counter first if your model is equipped with it) use water ONLY to clean the tracks and shells and then dry the parts before re-assembling. For PB-688 series models, you may also reverse the two inner tracks to make your Spinner spin as smoothly as new. Verify Genuine NSD Products Counterfeiting is a form of fraud that deceives you into buying poor quality and unreliable products by stating otherwise, and offers none of the quality and reliability that comes with an Original NSD Power Spinner. To protect you against such fraudulent practices, NSD has taken steps to ensure that the products you have purchased are adequately protected with security "NSD" marks on the shell and the Printed Circuit Board, PCB, in the Digital Speedometer to prevent counterfeiting. In addition, all NSD Model Numbers start from two capital letters "PB" (ex. PB-688AMLC Purple). On every single packaging box and user manual, you can find mainly international patent numbers that NSD was granted. You may also spot a counterfeit by the following: Missing NSD logo on product or packaging; Signs of repackaging; Rusty PCB in the digital counter; Questionable price and Poor quality. ***To help consumers distinguish genuine NSD products from knockoffs, NSD markets and promotes its products with the names, "NSD Spinner" and "NSD Power Spinner," in North America. *** NSD has developed many patented innovations below since 1992: Classic NSD Power Spinner, PB-188 series, in 1993 Battery-powered Speedometer, SM-01, in 1998 Fluorescent NSD Spinner powered by an inner generator, PB-188L series, in 1999 LED-Matrix displaying top speed Spinner, PB-188P, in 2004 Formula One cars' engine sound effect Spinner, PB-188S, in 2006 Metallic NSD Spinner, PB-388 series, in 2008 AutoStart NSD Spinner, PB-188A series, in 2010 Multi-color lights NSD Spinner, PB-188ML series, in 2011 Bluetooth enabled NSD Spinner in 2012 AutoStart & Fluorescent featured Spinner, PB-188AML & PB-188AMLC, in 2013 Precision Sterling NSD Spinner, PB-588 series, in 2013 Break-Resistant NSD Spinner, PB-688 series, in 2013 Battery-free with Amber Backlit LCD Screen Speedometer, SM-02, in 2013 AutoStart & Break-Resistant Metallic Spinner, PB-888A series, in 2014 The NSD Highest Standard Decades of NSD research have achieved performance innovations for the world’s ATHLETES, TRAINERS, and RSI SUFFERERS.
