DjuiinoStarHeavy Duty Gyroscope (Solid Metal Rotor): Sturdy and Stable (Provides Good Gaming Experience)! High-End Office Toy, Addictive Science Gear DG-5PRO-06

Stupendiously good quality, runs forever. Good instructions and extra materials included.

Good quality. The grandkids enjoyed watching the gyroscope defy gravity. On the downside - it was hard to thread the string through the hole in order to wrap the pull-string to spin the scope. Young grandkids were interested but definitely requires an adult to thread the gyroscope and pull the string with enough force to make it spin.

I haven't mastered this gyroscope yet. I have to learn to wrap and pull the string properly.But it is high quality and exactly what I wanted and expected.My box was a little damaged when received (4 stars) but the product was perfect. Also, it came packed with the styrofoam peanuts which I didn't really like.

A diferencia de otros, el cuerpo del gyroscopio gira menos. Muy buen acabado. Silencioso.

I bought two. Neither are in balance, and will not work as a gyroscope. Waited too long to return. Piece of expensive junk.

very well made

Good quality but difficult to get the string threaded on the disk. I bought it as a birthday gift for my grandson and he’s only 6. He’ll need his father to get it working right. It will take a lot of practice but it really needs the help of an adult.

Extremely cool looking, fairly solid and weighty. The fit and finish isn't extremely perfect but good enough for the price range I guess. Huge problem with the breast ring flying out while it's spinning and scratching everything until you can stop it though. It's unfortunate because it's very cool looking if they would had adhered it in a way that was balanced it would be perfect. I have hesitated to do much more than press it back in and try not to turn it upside down since adhering it might cause it to be imbalanced due to where the adhesion Settles.
