Benning power cables?


I tried Searching everywhere but can’t find any comments on the benning 10awg power cables sold here on marketplace. 
Anybody have one? Any comments?

I own two power cords made by Rich out of Montreal, QC. I had Rich make me two 12’ power cords and a pair of 12’ speaker cables. Excellent workmanship, great communication, fast shipping and all for a very reasonable price. I’m currently powering two Sumiko S.10 subwoofers with the power cords. I have not had the opportunity to try the power cords on other components as of yet.
I should add that as far as I know items are made indivudally as they are ordered.
