I usually use rather expensive flatwound strings, so I am far from an expert when it comes to roundwounds. However, even I could easily tell that these are excellent strings for the money.
My only gripe is that they needed some time to stretch out before they stayed in tune, but this may be normal with a set of thin-gauge roundwounds. I expected an improvement over the old and rusty set that came stock on my Harley Benton, but the difference was night and day! I could not believe how much better the guitar sounded with these strings.
Also, the tension feels pretty even, and they are a joy to bend on! Time will tell how well they hold up, but for now, I am more than happy with my purchase. Finally, one thing I especially like is that the packaging is hermetically sealed, so you do not have to worry about where and for how long you store them — they should never oxidize.
