Got just one pack of these to test them out, now I regret not getting more than one. Decent strings, especially when You factor in that they cost but a third of a regular pack. Of course they will not last as long as coated strings, but just having these as a backup is great, not everyone can afford to change the entire pack every time a string breaks, and these fill in that slot perfectly. Plus, as they cost so little You can just change them more often, thus alleviating the need of coated strings to a degree. Furthermore, they aren't bad in any way, they keep in tune, intonate, feel nice on the fingers and most importantly sound good on the lower (B, F#) strings. Also some fatter strings for guitar tend to muddy up really fast, not the case here, I've had them on my 8 string for a couple of weeks now and they still sound great. Really can't complain, glad that Thomann provides something in this price bracket. Also, on a side note, for anyone who bought the R-458MN WH Fanfret, get a pack of these and change the strings the moment you get the guitar - the lower register will thank you!
