That's the short version. I'm a professional orchestra musician. These strings are among the worst sets I've used on my violin. The sound is a 4 of 10, power 4 of 10, not to talk about intonation stability. Not even close to what I read in the advertisement, specially the a string doesn't want to stay in 442 for just one minute. Big mistake when I think of the price. First and last set in my opinion. For half the price, there are plenty of options better than this one
