Product review (5 stars): very good quality
THICK beefy line, very good quality.  Note that the ends of the leads do not have a closed circular end but are more like "forks"..  in my case I use a plier to flatten one of them down to get it into the grounding strap on the samsung range.

i installed this with no problem and then watched how the cable wanted to lay naturally, so i ended up installing my NEMA 10-50 recept with flat ground pin parallel to floor and the outlet basically sideways super low to ground.  works great!!
