Fair enough.
It's worth noting that whilst the plugs on these aren't Anderson brand, they aren't non-branded generics either.
"aitm connectors" which is unsurprisingly a Chinese brand. They look and feel okay to me.
All the companion and Primus stuff I've seen before has AITM branded 50amp "Anderson style connectors" they seem to work OK, but one thing to note, their red coloured Anderson style connectors are the same as, and only fit the standard grey Anderson plugs, they will not fit the red colour coded genuine Anderson plugs, see attached photos.
The photo with the two red plugs has the AITM branded one on the left with a Primus branded regulator attached and a SMH/genuine Anderson plug on the right, as the photo shows they are not compatible and will not fit together, the other photo has a grey Anderson plug which does fit the AITM branded plug
