I've been using Savarez string for more than 10+ years and that's because it's made of high quality. The sound is superb and the touch of the string when playing (especially classical) is like no other. The sustain is good, tension is perfect, and you just can't go wrong with these strings.
I've used it all throughout my music university days, concerts, teaching, everything!
Pros: tone, tension, quality
Cons: none
Don't hesitate to buy them!
