Innovative Gyroscopic Resistance Training makes it easy and fun to exercise Anywhere

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. ***

This is the best device I’ve used to rehab my hand/wrist. I’ve had 2 surgeries for an injury which included a trapeziectomy with LRTI, vein ligation, median and radial branch nerve excision and burial, median nerve entrapment release, palmar tendon release, and scar tissue removal. Recently my therapist told my dr I was coming to the end of therapy being beneficial. I didn’t accept that and knew there was still more work to be done. Luckily, my husband had been through work hardening for a back injury many years ago and had paid attention to what other pts were doing! He talked to me about what he’d seen and I immediately started searching for the devices he talked about.

!! SURPRISINGLY EFFECTIVE !!

After being on the fence for over a year I ordered it. Surprisingly this thing works. I’m actually experiencing OMS in my forearms and wrists. Deep inside the muscles and I feel as if the tendons are getting more taut. This is a very good soreness. Grip feels firmer too. This will work on the mat AND on the range. Relieved some of the thumb joint soreness too. This is one of those “I should have bought this sooner” items.

Excellent

Looked at the 1 star reviews, and was prompted to post 5 star. Don’t know how long my NSD Spinner will last; I am using it several times a week. I liked the spinner so much that I purchases a second one for a friend in wrist/arm rehab. We are both enjoying this immensely. If it breaks, I will probably purchase a more expensive one, probably from NSD, as looking at the one star reviews, I find NSD’s customer service responsive.

Once you get the hang of it, it works well.

I didn’t know how to use it at first so I chalked it up as a lesson learned but one day my son picked it up and said whats this, I said it’s an exercise ball that doesn’t work and as the words left my mouth he was using it just like the guy in the video. Surprised the heck out of me. He then showed me how to use it and I’ve been using it ever since. Smartass kid. Anyway apologies for the first review, it actually works well and I’m pleasantly surprised.

Ideal for Rock Climbers.

I love this little gadget. I can spin this while I’m bored at work or if I’m watching something on Netflix. It definitely gives my arms a good burn. I would recommend this to all the rock climbers out there who want a little forearm exercise. I think it also helps strengthen wrists too.

Good for what it is – buy the right model

For what it is and the price, it’s 5 stars. I was playing with a friend’s auto start model and figured I’d try this one. I didn’t realize there were differences in models, so pay attention when ordering. I have no problem starting this with the cord, but also started the auto start on the first time…which some people struggle with so if think it’ll be tough to start, get the other model.

Love it.

I love using this exerciser. It’s a lot of fun and if you spin it as fast as you can it will work your forearm and wrist out well. The only change I would make would to buy one that has the auto start feature so you don’t have to have the string. You can start this one without the string but it’s pretty hard to do sometimes.

Oh Yea.. Feel The Burn!

I bought this NSD Power Essential Spinner Gyroscopic Wrist and Forearm Exerciser on a whim after trying numerous exercises, wraps, lotions, salves and meds to deal with experiencing prolonged pain from forearm muscle damage. My expectations were low so I’ve been wonderfully surprised to find that the pain I’ve been experiencing for near a year has gone down greatly in the course of less than a couple of weeks. I’m being careful and am following instructions I was given. No more than thirty seconds at a time, for three times a day max, with a minimum of an hour in between has resulted in something wonderful happening. I don’t understand what it’s doing, but I’m thankful it’s doing it. If all’s good at the end of two weeks, I have a green light to increase from thirty seconds a pop to a whole minute. A minute might not seem long, but I am telling you, that if you haven’t been doing any wrist or arm muscle strengthening, a minute will be a goal that you won’t realize right off the bat. Yes, it takes time to get it going right. It was downright annoying the first couple of days, but like anything, keep trying it gets easier and easier. The spinner came with 2 starter cords and I’ve lost one already when it flew off after a particularly hard pull. Another surprise was realizing that I’m feeling it in my bicep too. When I get up to some real extended time for multiple times a day, I think I’ll be seeing some major toning up all over my arm, not just the wrist and forearm. Need to workout your arms a bit? I highly recommend the NSD Power Essential Spinner as an introduction to toning and a prelim to lifting.

I am a musician and use this product regularly to strengthen my forearms and thus help prevent weakening tendons (which can lead to tendonitis). It provides a good workout and is fun! Try and do more reps on your weaker side. I count in seconds — usually around 15 seconds — when I do my workout. For me, my left arm is weaker and cannot make it spin as fast.
