I have to admit it, these strings are really excellent, I happen to like how they sound, they are very pleasant to the touch and after MORE THAN A YEAR (!!!!!) I can't notice any difference in sound and touch! Only the G string MAYBE (but I'm not sure) is a tiny little bit more hysterical to tune than when it was new, but the G string is a notorious pain in the ass to tune in any scenario, so this isn't really an issue. And my guitar stay in tune for days anyway, as she always has done.
So, are these the perfect strings? Well... I'm not sure. If you just want to mount them and forget they are on and just play for months and months then they are. But if you are like me and need some "quality time" to spend with your guitar(s)... nurturing the fingerboard with precious oils... polishing the lacquer with essences that Stradivari would have killed for... touching her in hidden places... all those maybe unnecessary but for me important things... well, with these strings all these things are gone. And I really miss them badly.
Conclusion: I can't honestly give less than 5 stars for the quality and the sound of these strings, but... they are simply far too durable for my taste, hence the general three stars. But if you need strings that simply don't wear out for at least MONTHS then the Polyweb are the s...
