QJ
From Sega Retro
QJ or Quality Joystick was a brand of video game accessories active in the 1980s and early 1990s. Its origins are currently unknown, though the brand was owned by Recoton towards the end of its life. QJ mostly produced joysticks for home computers in Europe, though also supplied the Sega Master System and Sega Mega Drive with accessories.
Some later QJ products were manufactured by STD Manufacturing, which had been bought by Recoton. The QJ brand was later dropped in favour of InterAct, presumably because by the mid-1990s, consumers were no longer looking for traditional joysticks.
