I'm very picky about what I play for strings, but even for the price of these strings I have found that they are really nice. No dead spots, and they stretch really easily, and hold a tune well. I've never broken these strings. I've had then on my 4 string for almost 7 months now! I even took them off and boiled them and they went on great and played like new again. I've broken almost every string out there, from low to high. These are great strings, they even held up through a lot of slap bass.
