Well, I'll try to be objective because I am relatively edgy. I bought these strings there one week. And I already have one who farted, how to explain how I'm bummed? For that is the feeling. Too bad, the sound is really good, they are nice and do absolutely no harm to the fingers when playing. So either it's me who did a bad thing by putting them, or I have had the misfortune to come across bad. Nobody will ever know. Too bad, I liked them. It makes me a little sick to have put 9 euros for not being able to play only one week. 3 stars for sound.
