B Bearing Drive. I just want to find out if there are any differences. I have Hasbro one, it does not seem that has ball bearing embedded. Does anyone know Takara Tommy has a real ball bearing in it? Thank you in advance for any inputs.

There have been no reported differences (performance-wise) between B: Ds of two different companies.
Except that Hasbro ones tend to have a higher chance of offering greater solo spin time (this too, was probably a rumor).
So yeah, that's that.

Oh, and you do not need a thread for this. Search around or visit Ask A Question Get An Answer thread.

And yes, it is supposed to be a ball bearing, as can be seen on the CoroCoro scans.
