For the price, these strings are pretty great. I normally buy some Daddarios for about 4 euros more, and they're slightly better quality, but not by much. The only issue I have with these (compared to the Daddarios) is that they seem to take a few days longer to settle into staying in tune, and they're not quite as good when it comes to intonation on the top three strings, but this is almost certainly exacerbated by the fact that my guitar is travel sized, so I can forgive them!
Basically, if you want some cheap ball-end nylon strings, then these are probably exactly what you're looking for.
