I'm a smart engineer so I know what I'm doing. That being said, this cord just won't work if there are other extension cords of the same type and different brand. There is simply no connection between the two ends. As far as I know it can even be filled with sand. Mine may be "faulty", but I've never heard of "faulty" cables. Completely unacceptable. If this works for someone, I would ask if it really works at an optimal level. Seriously, just avoid it or risk getting "failed" or something with sub-optimal quality/early failure.
