The TOPSPIN Precision Spinning Top is extremely precisely—it is not even allowed the deviation of circularity or coaxiality, even by 0.01mm(0.00039 inches).
Therefore, it spins for a really long period of time. Under our inspection condition, it spins longer than 3 minutes on average (the length of spinning changes depending on how you spin it and what you spin it on).
Please note that if you drop or hit the Spinning top against the ground, the tip of Spinning top may break and lose its balance.
