One of the things I like about ukuleles is how little you need to start playing it: little space, little skills and, yes, little money (little hands are a plus too).
This set of strings comes as cheap as it gets, and it totally does the job. For 99c you can't go wrong!
Great for practice ukus. Use them to play at home, etc... Probably not the best for a more "professional" use. If you want to get the best sound our of your ukulele, you better throw a few more bucks in.
Bottom line: add one or two of these in your next ukulele related shopping list. It's less than 1eu each and you'll be glad you have these around.
