When I saw the PMR's video review I commented, that I've seen that clicker before. Another thing I noticed was the reel foot, what I missed was the etching on the side. Shame on me for that, I must be getting old. I am again surprised by PMR's lack of knowledge, he should have seen this. Ladies and the gentleman the Rover is not a KastKing design, it is a Ming Yang. I confirmed this with a look at the MC500/600 schematics while it was apart on the bench. The black reel is a Ming Yang. Took it to a nearby lake to see how it would cast. I mounted the Rover on an Ugly Cat, set the spool up with a little side play, gave it two practice casts with a 3 oz. weight and then let it fly. I had to lightly thumb the spool once during each cast. Not a record breaking distance but probably enough for most bank fisherman. When I got back and opened it up I found the brake weights were pushed in, so they were turned off. So I didn't have brakes or spool tension. Use the brakes and it should be a very easy caster but not a long distance reel. While I was reeling in I noticed a lot of visible play in the line guide. Well, that is something that needs checking. The pawl and worm fit together well so that is not the problem. I've seen 30 yr old reels with all the chrome wore off the shield that had less play than this line guide. There's .032 of play between the line guide and shield, that is not good. It's a condition that is not going to promote longevity. I described the original Ming Release mechanism as the cheapest collection of pot metal I had ever seen in a reel. This is an improvement, I see nothing wrong with it, as long as the metals are well matched to prevent wear. There is a single spring on the mechanism. It functions in a typical fashion, a metal piece slides under the yoke to disengage the pinion. Then two springs return the yoke to the drive position.
