How long have you use it?
Six months they are on my guitar, and not a single mark oxidation

Have you tried many other models before buying it?
The D'Addario original Dunlop and Dean Markley

What is the particular feature you like best and least?
Most: currently no oxidation due to 5-6 hours per week. A ringing sound that I love.
Least: the price!

How would you rate the quality / price?
Listed in time, but paying 2.5x the price of a normal game it hurts instantly. So to see if the strings can really last.

With experience, you do again this choice?
Yes, I have to take for my new guitar. Hoping that the result will be as good.
