Here's a written explanation of the various versions of the Renegade...

1st-generation: dull black plastic, hex nuts, and spacers prone to string slippage.

2nd-generation: shiny durable plastic, star nuts, revised spacers that prevent string slippage (spacers are aluminum, btw). Says "SuperYo Renegade YoYo" on the side.

3rd-generation: similar to the 2nd-gens, but has a smaller string gap and says "SuperYo! superyo.com Renegade" on the side.

4th-generation: similar to the 3rd-gens, but comes with one brass spacer and one aluminum spacer. This restores the string gap to the size of the 2nd-gens. Also made with new molds that (1) make the star nuts fit tighter so they don't fall out when you unscrew the yo-yo (2) allow for a smaller string gap when the yo-yo assembled in the imperial shape.

5th-generation: these are the marbleized/glow Renegades. Similar to the 4th-gens, but a stronger material was used for the star nuts. Some of the newer 5th-gens come with two brass spacers, instead of a mix.
