Good quality
Perfect running and nice sounding G string. This was the only string set so far that did not require any adjustment in the saddle to get perfectly in tune across all the neck.

Love the monofilament G string!
I've used the D'Addario Composites on and off since they debuted in the early 1990s. There are more strings choices on the market than back in the day but I always come back to the Composites. The tone is a traditional mellow timbre, similar to Dynacore and the standard EJ44, but with a brighter sounding G. The problem with nylon 3rd strings is they tend to be too mellow—even dull and tubby—and this tan colored monofilament has more bite. So better for lyric solos up and down the 3rd (G) string and a smoother transition between bass and treble timbre. A nice thing about the monofilament 3rd string is it almost lasts forever. The other trebles will be scratched and worn, losing tone and sustain after a couple weeks of hard playing but I can leave the 3rd string on through many changes of basses and trebles. Be careful when winding up to pitch as both the bass and monofilament 3rd string require about 75% fewer turns to hit pitch than standard nylons. If you simply turn the tuning key the amount of turns standard strings need, you'll be an octave high and break a string. Finally, the both the bass and monofilament 3rd string stretch out quickly, holding their pitch much sooner than regular nylon strings. The two upper trebles are just standard nylon so they stretch forever.

Complementary to Mariachi/Flamenco
These strings are simply great sounding and last forever! Mariachi guitar player for over 10 years. These are the go to for flamenco style music but also go great for jamming out to acoustic classics or rock and roll! All in all great strings! Gotta love the composite g string!

Strings feel and sound great!
No, I'm not a classical guitarist but, I do play steel string guitar. I use them on my Tenor Ukulele. I just use the D, G, B and E strings. Yes, I use low G tuning. Hint for D'Addario to produce a set of 4 for the Ukulele players. They feel and sound much better than any Ukulele strings I've tried. These seem to be louder as well. It makes the Ukulele feel more like a guitar which I absolutely love. Yea, I got the idea from the entertainer Jake S. from Hawaii.

Sounds like a much bigger guitar now!
I have a Breedlove nylon string acoustic. Not a classical but a hybrid. It was a little thin on the lows and a bit too bright in the treble. These strings do exactly what they say. Elevated, commanding lows and smooth mellow highs. Much better projection and string balance. I like the added string tension. Great strings!

easy to loose
Both sets of strings were 5 star once I found them. Amazon shipping packagers need to pack so that small items like Guitar Strings do not get lost in the packing material.

Decent overall
These are decent strings with good projection. The composite G is quite good. Tuning stability overall is subpar though, as I have to retune after every song, so I think I will switch to a different set.
