DjuiinoStarHeavy Duty Gyroscope (CNC machined solid steel rotor): Stable and sturdy (pass second floor drop test); long spin time (more tricks); premium fidget toy, magic

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.

Seems to be well made. Black chrome color is very nice. The string option for winding, however, is somewhat tedious. Pulling the string to wind exposes wrap gaps, so much care should be taken to wrap winding very tightly. Not a bad thing, just not what I had in mind for an office/desk toy. Time consuming to operate. I'm probably looking for a rip strip style wind up.

It looks nice and works pretty well, but within an hour of opening the box, my 10-year-old had broken it. The metal is fairly brittle, at least on the black one. It still works, but this part is broken (see photo).
