Review on DST-820: DjuiinoStar Premium Spinning Top - CNC Machined From Solid Brass, High Precision Desk Toy (AVG 5-8 Min. Spin Time, Best Record 11+) by Aaron Leburu

The top is well built, heavy, low center contact profile, and as the title says spins for a very long time on a concave glass spinning base.It stabilizes quickly with a smooth gyroscopic pull to center, and you sometimes have to take a second look to see if it is actually spinning, or if it's standing still, on the glass, frozen in time.
