Review: Makes exercising your wrist and forearms fun - Of all the things I saw at CES, this was the only item I decided to buy. I actually found their competitor, DynaFlex Powerball first but decided to go with the NSD Spinner brand instead because it sounded like they were more on top of customer service. I also liked that they had an affordable wind up version that didn't require using the cord. You wind it up by turning the ball in the direction of the arrow (see picture attached, the arrow is embossed into the green part.) I'd read these kinds of balls were popular with rock climbers as a forearm exercise and it was fun to use, so I decided to give it a shot Pros: - Don't have to worry about losing a cord. You can take this thing with you anywhere and give it a spin. - Easy to use - I find myself picking this up while I'm watching TV or just walking around. - Helps with wrist / forearm pain - I have pretty bad pain from using the computer too much, and I found using the ball helped me stretch my forearms and hands and helped reduce the pain a lot - I can't validate, but when I have the ball spinning on high RPMS it takes a lot of effort to maintain my grip on the ball so I feel like I'm doing something to build up my strength. Cons: - If you have sweaty hands like I do, it's sometimes tough to wind up the ball - Very confusing lineup of options. I recognize in the end reading and taking note of the titles is super important. Here's an overview of the lineup - ~$20 : NSD Power Essential Spinner = regular ball, no counter to show rpms, no self starter, vibration free to 15,000 RPM ~$30 : NSD Power AutoStart Spinner Gyroscopic Wrist and Forearm Exerciser with Auto Start Feature = regular ball, no counter to show rpms, w/ self start, vibration free to 15,000 RPM ~$40 : NSD Power Winners Roll and Spin Spinner Gyroscopic Wrist and Forearm Exerciser with Digital LCD Counter and Auto-Start Feature = ball w/ rpm meter, w/self start, vibration free to 15,000 RPM **what I got** ~$50 : NSD Roll 'N Spin Rainbow Lit AutoStart Spinner Gyroscopic Wrist and Forearm Exerciser with AutoStart and Multi-Lit LED = = ball no counter to show rpm, w/ self starter, has LED lights that light up to different colours depending on how fast you're spinning, vibration free to 15,000 RPM ~$75 : NSD Power Winner's Precision Sterling Spinner Gyroscopic Wrist (SILVER COLOUR) = ball w/rpm meter, NO self starter. Vibration free to 15,000 RPM. Delivers more resistance than the plastic balls. Inertial resistance: 19kg at 10,000rpm (350Hz) 3.2kg at 10,000rpm (450Hz) "up to 41.3lbs" ~$75: NSD Power Ultimate Winner's Precision Sterling Spinner Gyroscopic Wrist (GOLD COLOUR) = ball w/rpm meter, NO self starter. Designed to deliver higher RPMS. Claims vibration free operation at up to 27,000 RPM. Overall, since these aren't expensive, it was worth it for me to try out. Update: I still love this ball but I recommend not leaving it anywhere really hot. Since I take this ball with me everywhere, I'd left it in the car overnight in the hot summer weather and I think the glue that held the grip band to the ball melted. Now I can't keep the rubber grip on the ball when I spin as easily.
Review: Excellent - I bought two of the cheap 15 dollar spinners and they are absolute junk. Sent both back. Could not get one of them to consistently work. You get what you pay for. This unit works flawlessly and easy to keep spinning. Do yourself a favor buy this first and skip the cheap spinners that are not worth receiving even if they were free.

## Questions & Answers

**Q: Why is this unit more than twice the price of the "acelete auto-start 2.0 power ball wrist trainer ..." ?**
A: I can attest to that. My NSD powerball lasted four and a half years. With the same amount of use, my Acelete lasted only a month and a half.

**Q: noise level ? can I use this at a silent environment like office ?**
A: Yes.  Our surgeons use them in their offices while on the phone.  It makes very little noise. Sort of a brushing sound.

**Q: does it have led light ?**
A: No, all NSD Spinners with ergonomic/rubber band in black are not equipped with LED lights. However, the Speedometer on the top goes with self-powered back LED light when you spin and reach 3,000 RPM.

**Q: What is the difference between the nsd power and nsd titan? the price is as twice as big for titan**
A: Their Material and Size are different. PB-688 series Spinner are made of military-grade plastic while PB-888 Titan series are made of zinc rotor and  Aluminum Alloy shell. PB-688 is a tennis ball sized Spinner while PB-888 is as big as a softball.

*by R***W on August 13, 2015*

The NSD spinner is a great tool. There is no one trick pony and this isn't it. But grading this on the terms of its role and effectiveness at that role, I would give it a thumbs up. It is a multi purpose tool, it can help build strength in basically anything below the elbow, maintain range of motion in the arm and wrists (shoulder included, don't just hold it one way!), and help practice finding a rhythm which can be important from the average joe at the desk to an athlete. I play sports, and this helps build the fine motor control in my offhand (fine vs gross motor control, look it up!). At the computer, it is the perfect gadget to play with and use for loading screens. I purchased this version over the others because it has a screen so you can get some feedback on what you're doing. For my grip, holding it when the screen is touching my palm, is most secure and comfortable because I have the most direct contact as possible. If I flip it over so I can read the screen during use (if you're constantly spinning it to keep it powered, it is hard to read by the way) my palm cannot come in complete contact with the bottom because that is where the spinner is exposed. In conclusion, having the screen is a great perk but you really could do without it. I'd strongly recommend the self starting mechanism this one has versus the other options that require a string.
