JoyTech Precision Gyroscope Metal Anti-Gravity Spinner Balance Toy Educational Gift AG002

Works pretty well. It’s really fun to play with but it would be nice if the flywheel was heavier like some more expensive ones to increase the strength of the effect. sometimes it starts vibrating and making a very loud grinding noise but that can usually be fixed by shaking it gently. Overall its pretty good for the price and I would define Italy recommend

TLDR; DO NOT BUY THIS GYROSCOPE! Spend a few extra dollars to get a higher quality one, don't make the same mistake I did.Straight out of the box it clearly has a very loose tolerance and no quality assurance. It looks nice but the centerpiece has play in every direction and isn't properly balanced. Once you let it rip it vibrates violently and loudly which means it looses its momentum way faster than it should and is harder to balance to do tricks.I have a bachelors in physics and have taught the science behind this a few times (meaning I have gotten my hands on a handful of different versions of these). With that being said if you want to get the full experience you really need to find a half decent one of these and this one just isn't it.

I do not recommend this product. The quality is terrible. The gyroscope’s disk is warped, and the components have extremely low precision, resulting in significant vibration and a rapid loss of kinetic energy. Very disappointing purchase.

It’s takes some practice to really get it going and I almost broke a window when it went flying out of my hand. But once you figure out how to get the spinning going it’s pretty cool to play with.

Not sure if i got a defective one or if it is damaged somehow, but it does not stay balanced like a gyro should. i get it running and stand it up, and no matter how careful or balanced it seems to be, it quickly leans to one side, as soon as let go of it. does not stay upright at all.also, may be a bit of a nit pick. but the ball/string/puller i got was pink and not yellow like the photo showed. i understand that there may be some differences, but i chose this one over others specifically because the rip cord matched and would display well togetherSeems like i won't be displaying it as much as i hoped so I guess that doesn't matter as much now
