Another advantage not least, there is absolutely no oxidation or other deposit "harmful" on the ropes! So finished passing a soft cloth to remove sweat after playing, I who sweats a lot of hands when I play, it makes my life a lot and playing comfort is all the better.
And finally, the life is simply outstanding. I play almost every day and my cords are mounted for 5 months on the guitar, the sound has not deteriorated and has not lost its consistency.
In short, after being put off by the price (2x superior to other brands), I finally decided to test this brand and I believe I have found MY reference strings.
