Precision Gyroscope (colors may vary)

Built sturdy enough for kids, and works well.

I needed a gyroscope for a physics class I was presenting. I had the classic metal gyroscope, but it had bent and no longer spun reliably. This is a great substitute - the plastic frame is more "precise", and I love the plastic zip pull for getting it going. Far faster than wrapping a string (though that is also an option). It does vibrate a bit - it's not quite precision, but it works. Also, the hole for the string was blocked with plastic flashing, requiring me to cut it out with an X-acto blade. But it's not that $250 gyroscope you can find on Amazon either - it works well enough for the price.

Bought this for my just turned 5 year old Grandson to demonstrate how the "gyro-helicopters" and "drones" work. He is a kid with everything and is deep into Legos. We watched the videos and he was super excited about getting one. Not being in the stores, we had to wait for delivery. Every day he was filled with anticipation of this "magical gift" He actually got a new bike for his birthday and shocked his parents by only asking if the "gyroscope" had arrived. The gyroscope came in his favorite color "neon green" and it was an immediate hit. The gyroscope itself works flawlessly and can actually spin for a couple of minutes. We purchased the old string model as well and this one is certainly better built and the pull piece made it easy for him to use it with ease. There probably are not enough words to express how much he loves this "toy" He gives shows to whoever is around showing the tricks and spends countless hours just spinning it in every variation. Three months later, I see him during my calls on Facetime, still being obsessed with and showing me his latest trick. When I say "trick" he actually is dropping the spinning gyroscope on the floor and it just spins away. I strongly recommend this gyroscope as a great teaching and fun filled toy.

Didn't work well. Its unfortunate that choices for gyroscopes are limited to either super cheap (and low quality) or super expensive. This one was not even worth the low price I paid...and I would have paid more. Can't someone offer a decent one for $20-$25? Each spin lasted only a few seconds before it lost momentum and became unstable. Also, it vibrated so much that it would not stay on a hard edge. The stand is so light the gyroscope just sort of falls off of it.

Nice can stay for a good long of time although I stepped on mine and it broke the ring I put it back still spins really good just not as long very good and easy to spin you don’t need to use a string like the old one which I like more but if you like it more you can still youse the string if you like over all very good product would get again.

Wanting to give my grandson a retro toy, this gyroscope seemed perfect. It comes with a string pull start as well as a plastic T-handle gear strip. Using the T-handle was by for the best way to get it spinning but it was very hard to hold the gyroscope and then get enough torque with the pull. It was very tight and almost impossible for an 8 year old. Once we did get it spinning, it's balance was far from precision. In fairness, the balance may have been thrown off by our intense grip holding it when pulling with the T-handle. The housing is plastic which could have easily been altered by our pulling grip. Not the best experience.

It's heavy, which is good, it gives a more definite feel of the "gyro-power" that resists any attempts to move it. Flipping it upside down while it's going gives an awesome feeling as it 'resists' your turning. But ^^^ is if you're holding it with your hand. Which I can say was not the reason I got this. I, just like most of you I'm assuming, bought this to display it to friends and family on tables and such. (Quick note, the heaviness of it creates a momentum far far greater than any friction the lil black base displayed in the picture can have thus the base will actually be moved around by the force of the gyro, rendering it utterly useless. You'd have like superglue it down because I don't think any form of tape would be strong enough. Base = light and small, gyro = heavy and big) Anyways, the gyro I got was a green one, not a blue like depicted, but that was fine really. It came with a ripcord mechanism very very similar to bey-blades (toy tops) therefore, launching this thing is incredibly easy. There is a small hole and string included if you like to push this thing with like a kitestring or something. Given all of this however, there was one major flaw. The outer horizontal ring you see, the thin one, is un-proportional. One side of it is clearly larger than the other. This unbalance causes this gyro to quickly fall out of balance. IE: land on it's side/topple over. Gyros are supposed to stay upright or whatever position you put it in for a while, but the most I could get was about 60 seconds before it started wobbling and fell to its side. And that was with a complete upright stance. If you lean it at all, it's even less time. All the while, the gyro is wizzin all over the place like a beyblade if you put it on a flat surface. Obviously, this was one gyroscope out of many. But I do suspect that even if you get one that is perfectly symmetrical, any drop on it's side will bend the ring because it doesn't feel sturdy. Conclusion: it works, but not well enough to offer vastly more entertainment than frustration.

It is a very fine product which functions perfectly to demonstrate the principles of gyroscope. My kids love to play with it. A must have for teachers, parents and kids who want their kids to feel the magic of science.

O produto veio em perfeita ordem, td certo.

Some theories say that this toy and the gyroscopes, in general, keep their position when they run, because of the torsion fields.

The toy is well built and construction is reasonably precise. It is a good toy to demonstrate gyroscopic precession to students.

GREAT EDUCATIONAL TOY
