DjuiinoStar Heavy Duty Gyroscope (CNC Machined Solid Steel Rotor): Stable&Robust (Pass 2nd Floor Drop Test); Long Spin Time (More Tricks); Premium Fidget Toy, Magic Anti-Gravity Gear DG-5PROLite-02

It is a very nice toy. It was a big hit for a 13 yro boy who is a gamer and not impressed with everything 😉 I mean it’s actually pretty cool thing even for an adult! There is a learning curve for about 5-10 tries for a perfect spin but not hard. I will buy again.

Nice gyro, kids were impressed how it could precess stably at a ridiculous angle without falling over. The gimbles are really very well lubricated.One complaint would be the string to pull it. It has become frayed at the end after just a few minutes use. The instructions say to wet it, wax it, or cut it, so the manufacturer obviously aware. So far (one day) I can still insert the string with some spit and twisting, but I think that'll only be viable for another day or so. Not completely sure what it means to dip the string end in wax, or why the wax couldn't have been applied by the manufacturer. I'll give it a go later this week.

Solid design and long spinning.

For a muscled pulled gyroscope, Djuiino Star has produced a nice quality and aesthetic product. Its everything as described in the Amazon store page.You can easily spool the waxed string either clockwise or counter clockwise and spin the rotor either way. Nice observation debunking the Coralis Effect. While the rotor is spinning one direction you can also spin/twist the gimbal in the opposite direction.The gyroscope has decent rigidity for a hand pulled wind up. If it were powered, the rigidity would be stiff and stable like the ones in aircraft, but you know, this hand pulled. For hand pulled, it does a great job. The spin slows down over time and the gyroscope begins procession or you can force procession by tilting the gyroscope at an angle and it’ll maintain a tilt during the spin. There is no observable downward pulling force toward the center of the earth putting the gyroscope into procession. Instead, the spin slows down, and the gyroscope succumbs to its own density, being surrounded by a lesser dense medium, air. If there were such a downward pulling force, then 1.39842829E+22 newtons of gravity conforming the oceans to a ball would crush the gyroscope. So, either the gyroscope is fake or gravity is fake. The gyroscope and its density can be observed. Gravity is not observable.When running the string through the gyroscope, make sure you use both holes or else it wind up on both sides of the gyroscope. It’ll get tangled up using one hole.Easy to use. Allows easy observable facts about our reality. If you’re looking to get one, buy one from Djuiino Star.

I have the heavyer one and the lighter one out performs it and is priced lower.The best gyroscope of the many I have.Zero issues would buy more for Xmas presents for children. You need to stiffen tip of string to make it easier to make it through hole.Little super glue or heat with flame.String is nylon so flame will stiffen it.After many many hours never had issues with string breaking.
