We play in humid Malta, and I have sweaty hands. These strings are the strings to use when changing strings often and yet save on expenses. If I'm recording or have a particularly important gig I may use Elixir as my go to brand, but these are a third of the price (don't provide 80/20 bronze which is unfortunate to be honest), sound mellower (phosphore bronze) and last enough. There has been a time these didn't last long on our guitars and that's a bummer. I hope Thomann sorted this quality issue. Recently they have been fine. The plain strings tend to rust a bit, and feel as if the string is rougher kin of needs polishing(?) in a way so I'm pointing that out, but overall thumbs up...Forget coated brands like Martin, Tanglewood, D'addario...bang for buck these are great.
