I've seen 2 different styles magic boxes and 1 cable straightner. 1 magic box was about 1' long, 5 holes, handled up to .875, wouldn't straighten shit. second box was 2.5' 2 holes,.750 & .500 worked pretty good would straighten twisted or wee-wah'd cable pretty good . best one was hinged swing style ,I still have one. works great as long as you only put proper tension on it as it will elongate (that means stretch it out blueSKY) the cable. but it will dam sure straighten out twisted cable!! makes it look like pipe. the circus is back in town
