Odd. It seems they may have started using a different diode. Either that or your "520" is closer to 505 and this new pen is close to 520. The power output is also very odd seeing how the review units were all close to 5mW with I believe one or two pushing 10mW.
This is not about the LaserLands 520nm 5 mW laser, but a different pen that is advertised as being 510nm.
