Completely transformed my baritone ukulele from a "mushy" dangling sound to a full bright as well as bassy sound. The first two strings take a lot of time to settle in and expand greatly when tuning (don't leave too much of space when winding the new string for the first time, because it will expand by 10 percent or so and you could end up with no space for winding on the tuning peg). Sadly, the first string broke after 3-4 days of playing, so don't forget to check the nut and file a bit with an old string or a fine sandpaper if necessary. Also sanding the frets a bit and smoothing them a bit will help in the long run. These strings are a bit more "gentle" than your standard nylon set, so keep that in mind.
All in all, I really recommend the strings. Have a good play.
