Murex Zodian Universal General Purpose Welding Rods 3.2mm

First I'm going to state that I am a hobby welder, self taught. I deceided to treat myself tosome expensive rods to see if it made a difference to my welds, I don't think so, seem the same as the cheap ones to me. I'm giving them 3 stars as they do the job but are expensive, can't see the point.
