I had a set of green ones on my FerLembic guitar for about six months. No problems with flaking. If regular strings can be characterized as sounding 10 when new and fading to 1 after a couple of months, or so, the Neons started out as a 7 and faded to a 4 after 6 months. Much more consistent, but never sounded as good as new regular strings. I could see them perhaps working better on a bass. But they sure do look cool. The green ones really fit in well with the cannabis leaf inlays on my guitar!
