those string does sound amazing and even with lots of playing the will last quite long! The sound is smooth and still full of brilliance and brightness without sacrifing a nice and controlled bottom end They are pretty less expensive and are made in germany, buy them if you like to support european made products and for their great sound.
I normally use "Ernie Ball Regular Slinky" I also try this pyramid. Both of them are perfect strings. I can't say sound difference much because I don't have golden ear :) . It seems to be last longer than Ernie ball
