Good set of strings for a great price. Compared to other strings from D'addario, Gibson, and Elixer, these strings are a much better value since they are so cheap. However, in all the years that I have been playing, I have not once said, "man this guitar is great, what kind of strings are these?" Great guitars play and sound great, period, given of course that you are using at least decent strings. I know that every guitarist has their go-to strings, as do I (and the brands and styles vary across each of my guitars), but honestly strings are strings. These days, so much attention is paid to the manufacturing of these strings, that the quality and consistency is great across a number of different brands. Generally, I can't tell much of a difference in tone, playability, or "slinky-ness" across brands. (I can hear the groans now) Hear me out though, if I want to change the tone, I will get a different string gauge, and this is the same for slinkyness. In the end, given 5 sets of top notch strings, I will pick the fresh set vs. a worn set 10 times out of 10.
Pros: Very cheap for 3 sets of strings, that means you can change more often, which in turn means that these strings will feel and sound better longer
I feel like they definitely last longer than say Gibson vintage strings, but most coated, modern strings will be comparable.
Conclusion: Strings are strings, and given a good set of strings, I would only base this recommendation on price and great value (5 stars for that). If you are just starting out, I recommend you try a number of different strings to find your preference, but usually in a pinch whatever my local shop has on hand has worked just fine.
