DjuiinoStar High-end Fidget Spinner, Unique Dual Bearings Design, Pricisely CNC Machined (Stainless Steel), Luxury EDC Toy DFS-01

[See pictures attached to this review] This is a very high quality, well machined spinner. The dual-bearing system (one R188, one 6703 ring bearing) is ingenious and works beautifully. The outer thick body uses the R188, the inner cog uses a ring bearing (probably 6703). The two sections have a small amount of friction together, so if you spin one section alone, the other section will start moving too. When spun together in the same direction, they complement each other and add extra performance and feedback. I clocked table spin times consistently from 7-8 minutes, which is very good. Pros: - Excellent machining and finishing (stainless steel) - high quality shielded R188 bearing installed - high quality 6703 ring bearing installed - good weight at 111.7g - great size: 48mm wide, 17mm thick - dual-bearing system is innovative and works well - nice packaging: hard padded case, bearing tool, and several ball bearings that can be added to the spinner - multiple ways to spin and flick Cons: - may be difficult to find a backup/replacement bearing for the 6703 ring bearing - bearing tool is proprietary and unique, if lost it could be harder to disassemble (but still possible) - tiny 3mm ball bearings are easy to lose!

This spinner is very finely machined, and works beautifully. It's heavy and sturdy. I think the most fun is the independently rotating rings. I put the three larger ball bearings that came with it in the rings because I like the sound it makes. I also like spinning the two rings in a counter-rotating fashion, and watching the inner ring slow down, stop, and then rotate in the same direction as the outer ring. This spinner is very well made. I think it's worth the money for its uniqueness.

**Update 01-24-22 * I received a reply from djuiinostar who sent a replacement spinner. The new spinner works exactly as intended. Both the inner ring and outer ring spin quick and smoothly. This is a very high quality spinner with a unique design and memorizing dual spinning feature. Highly recommended and a must have for anyone who is a fan of fidgets. **Original Review *The looks and the finish is great with no hot spots. The outer most ring spins really good and is well balanced. The center ring does not spin freely at all. It appears that the buttons rub on the inner wall causing it to not spin well or for very long. You can literally feel and hear the metal on metal rubbing. It's a shame because it is a great design but unfortunately doesn't work as intended. *I have contacted djuiinostar but have not yet received a response. I will update this review if/when I resolve this issue.

This is a dual bearing spinner, the outside ring and inner ring are independent of each other and can be spun separately. The machining and finish are excellent although I can force the slightest wobble. This is due to the play noticed between the R188 bearing and finger hold (caps) shaft that passes through it. Although for under $100 I cannot complain as this really does not affect the operation of the spinner. When table spinning just the outer ring I consistantly get approximately 3:45. When I spin both rings simultaneously I see that time increase to 4:30 on average. This increase is due to the inner ring fitting into the inside 6703 bearing, therefore when the outer ring spins on the 6703 the inner race wants to come along for the ride; spinning the inside ring simultaneously reduces the drag on the outer ring. The weight is exaclty 4.0 ounces or 113 grams. It's got a little heft but I like gyroscopic feedback I get when rotating it while spinning. I haven't quite figured out what the ball bearings are for that came with it. edit: My best table top spin with both rings is now 5:16

Great quality, very smooth, easy to control because it's not big. spin time is only about 2+ mins on the table. if spin inner ring at the same time, maybe a little longer. compare to normal spinner with same quality, dual ring's spin time would be shorter due to the friction between rings. it's understandable. but still, it's far away from 7-8 mins. besides that, I like it.
