I used these on a Yamaha GL1 Guitarlele but have used the white ones on a classical guitar. They sound far better than supplied strings and last well. Once they have settled in they need very little retuning.
They play very well and ring out clearly. I would buy again

As the title notes, the strings are great and have a nice feel to them. However, they go out of tune really quickly -- every time I play this guitar, every string (not just the nylon ones, but also the lower three woven metal ones) are about a half step out of tune. Even after a few weeks, they never "settled" into the proper tuning. It's a small annoyance, so I only subtracted one star for this.
