Quality and Performance
Rapidity Beys look like regular beys, but on closer inspection may have cracked parts, the metal wheel does not dull because of use. The parts tend to crack and chip, Most of the Clear Wheels/Energy Rings will chip and look bad.
Rapidity may also pair the beys with some metal tips, these aren't real MF,MS, and MBs. These are entirely metal. they might have deformities because of of low quality work.
These beys tend not to work as well as real beys. For Example: Their Bearing Drive (Phantom Orion) does not have a bearing in it, cutting its stamina and Blitz Striker does not attack like the real one.
Also, all Rapidity beys are L/R.
These Beys tend to be quite cheap money wise, but you get what you pay for. Takara, Hasbro, and Sonokong are more worth the money.
