JoytechPrecision Gyroscope Kill Time Metal Anti-Gravity Spinner Balance Toy JA23

This gyroscope is the first one that I have ever gotten and I think it's easy to use and functions the way it should. After some practice I managed to wind it up easily and spin it without a problem. I've had it for about two months now and I have been spinning it multiple times a day. After all of that, it still works just as fine as it did the day I got it.The product comes with two strings and a ball for better grip when pulling it to spin (I soon took it off since I found that easier for me). Since I spun it so much the string soon became frayed and it was hard to insert the string through the hole on the axle. How I fixed this was by simply cutting the end that was frayed and taking a lighter and waving the flame over it just a little bit to melt the tip. This worked out perfectly so it definitely will last for quite some time (if the newly formed end would is too big to fit through the hole, I would use a nail file or something to sand it down until it could fit).There once was an incident where it was dropped from a table and landed on concrete and the disk popped out of it's frame. Fortunately, after some effort I managed to pop the disk back into it's frame, good as new. It did, however, take a bit of force to pop it back in. I was afraid of breaking the frame since I was pushing so hard but it held up just fine.The only problem that I came across (not associated with it being dropped) is whenever I spun it it would sometimes make a loud vibrating sound. This usually would happen if I stood it up perpendicular to the floor while it spun. However, after a quick readjustment the vibration stops (the vibration noise doesn't affect the spin function).Overall, I love this toy and it's very fun and easy to use! The tricks you can do with it will always amaze me and it's a fun little introduction to torque and precession for those curious minds out there.

It's a pretty cool toy, once you get it figured out. It doesn't stay spinning for too long, but my son did figure out it does spin longer if you do wind it up the correct direction.

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

got this for my grandson. all the kids like to see it work. nice heavy stand and good box included.

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.

My kids love playing with it. Recommended for kids who are curious and iterested in science or technology.

This little spinner is a great buy. Although very inexpensive, it is very well made. The brass rim and the silicon nitride bead on the bottom are features found on considerably more costly spinners. I’ve had this spinner just 4 days and have already gotten a spin time of 3 minutes and 15 seconds on a carefully leveled iPad. I’ve already ordered a concave glass lens for more convenient attempts at longer spin times. Basically, i have absolutely no complaints about my purchase. No, I recommend this little guy as a fine way to get addicted to the world of spinning! UPDATE: Well, with an inexpensive magnifying mirror used for makeup and eyebrow-plucking duties, i have now hit the 5 minute mark on spin time. It is truly bizarre — and great — that such a little chunk of pretty metal can become so obsessively time-consuming! I am a 72 year-old unstable former genius who loves his spinner — and the others which will follow!

Immediately didn't work, stopped spinning within 20 seconds. Lose, horrible tolerances. So it was replaced with a new one. Same issues with the replacement. Don't waist your money on this.

The media could not be loaded.  It arrived sooner than I’d expected. Small and nicely finished. So far so good.

Hasta el momento no he podido hacerla girar.

I love this little spinning top, great colours, it feels solid and spins for ages. I bought a couple as gifts but kept one for myself!

Bought this top for my daughter, but keep playing with it myself too.It's tiny (about half a thumb) and spins for ages.
