Help with hand pain

Easy to use. Hope it helps with hand pain.Why did you pick this product vs others?:Chiropractor recommended

Top Notch

Years ago I owed one of the plastic blue ones with the green ball. It was practical but the bearings began to go after a while. Now, years later I purchased this one and I'm well impressed. Reading the description, I did not fully realize the inner workings were all medal parts supporting the gyro ball. It does not require a pull cord to kick it off and is crafted with a spring mechanism that allows you to get it going effortlessly. It is a nice desk stress reliever and good forearm developer to boot. It is highly recommended and worth the extra change.

Works great

It works well, the directions are pretty clear, there is a learning curve , but once you’ve got it mastered it is pretty easy.

Good wrist and forearm workout

The media could not be loaded. Fun way to get a wrist and forearm workout while working. It makes some noise but not overly loud. Takes some time to get the hang of it but overall, really enjoy it.

Interesting and fun novelty exerciser

This is kind of a weird piece of exercising equipment, but I've found it useful and fun. I got it to help avoid additional tendonitis in my elbow due to archery. It seems to have done that, although giving the affected elbow some rest first also helped. No substitute for that. I have had no problems since I started using this regularly, however. I'm not convinced of its central role in that, but I do seem to have stronger support muscles all the way up to the shoulders as a result of using it. And because it's fun to use, I'll keep using it. I don't recommend using it if you are already having some pain. Rest the affected part and then start using this as a preventive measure, and keep using it. I usually do a minute in each hand, two times through, per day.At first it was hard to get going, but now that I've got the hang of it, it's pretty easy to get it spun up. I do better with my right hand- my left hand isn't as coordinated and I can't do the finely tuned rotation as well. However, I actually spin it faster with my left hand once I get it going, though I can't keep it going as long. The thumb wind-up start on this model is worth paying extra for. I wouldn't want to have to use a string to start it each time. It takes a while to spin down, so you can switch hands and get it spun up to speed again without having to restart it. The rubber band around the middle gets a bit out of position sometimes, so I flipped it upside down and leave a little gap so it rests on a ridge and it stays in place. Makes kind of a neat whirring sound when it's spinning fast. I wouldn't waste money on an RPM indicator- I'm not sure why you'd care.***April 2019 update: The ball stopped getting into high gear, so I took it apart and cleaned it (Three tiny screws; do NOT lube it with anything!). It worked for another month but now I can't get it to really spin up, so I'm ordering another one. 4.5 years isn't a bad product lifetime for something like this these days. By the way, it still spins, but doesn't go into that whirring, high resistance mode where it starts sounding like a prop engine plane when you get the gyro really going, and eventually it just slows and stops. Some people that complain it doesn't work may not be getting it to that resistance point- takes some practice- or they may have gotten a defective unit. You will definitely hear and feel the difference from the spinning when you first start it to getting it into that resistance mode.

Piece of junk!!!

I don't review many items, but I picked up this item on a Lightning Deal and thought it would be a nice tool to increase grip and forearm strength. This thing is a total piece of junk! I wound it up (in the direction of the arrows) as indicated, until it stopped. I then let it unwind and create its gyroscopic effect. This thing gave very little resistance. I don't think this would provide enough exercise for a 2 year old's arm, let alone an adult. It also spun down very quickly. I tried rotating my wrist (as indicated in the instructions) to increase the resistance of the gyroscope and it made very little difference. Even at a Lightning Deal price, this thing isn't worth it. It wouldn't even be worth it if it came out of a $0.25 gumball machine. I'm thinking that something that allows you to pull a ripcord and get some high RPM's might be much more beneficial. Steer clear of this item.

It's fun - But I don't know if it helps?

I am skeptical that this device is the solution to wrist pain when using computer mouses or similar devices 6-8 hours a day. But it's fun to use - In fact I find myself fidgeting with it whenever I have a phone call.I wish there was more rubber grip at the bottom of the device, as I sometimes feel like I'm strengthening my grip strength more than I am strengthening my wrist strength. Or make the device more ergonomic - places for someone's fingers to slot into? Might be difficult when people have multiple hand sizes, but these are improvements that could be done.Would I buy it again, even *if* just for the placebo effect? Yeah. But don't use it too much during a work day, otherwise your hand, wrist and grip strength, will hurt for the rest of the day!
