Here is my take. I bought some of these connectors last year. I have yet to put them into service. Definitely not up to Neutrik standards. The plastic parts are thin, I am able to squeeze the thread collar between two fingers easily. The smaller yellow part seen in the photos has notches so you can index the direction you want the cable to exit from. There is not a strain relief or locking mechanism of any kind. A cable tie will be needed. The black body is made from two cast pieces and welded/soldered together. May be done while the metal is still hot. Solder pockets feel and look cheap compared to Neutrik. Two additional bits, the cable hole is 5mm in diameter and the weight of the connector is 1oz/30gms.
Time will tell as to the fitment and usage in the field.
They may be ok.
