Aroek 2017 Fidget Spinner Toy, High Speed Up to 5 Minutes Spins, EDC Hand Spinner for ADHD, Killing Time, Stress and Anxiety Relief, Hybrid Ceramic Bearing, Stailness Steel

Great spinner. 2 - 2:30 spin times. Not bad for a clone.

Item fell apart the fifth day of use. The other brand fell apart a day earlier. I would not recommend these products.

Our longest spin has been only 2 minutes--nowhere near the advertised limit. We have tried cleaning the bearings and this helps bring it back to the 2 minute mark when it starts to slow down. I agree with the comment below that there are not enough bearings to keep this thing in balance; there is a random vibration that slows it down. There is also considerable noise indicating some friction. Probably some of the inner parts could have been polished better for smoothness.
