I got some of that stuff with my last string order. It's a little bit misleading actually, because with the coated strings like the Elixir's you just throw them on and away you go, and if you wipe them down afer playing they will last ages (well at least that is my experience with acoustic strings), however the Extra String Life bottle stipulates that you need to "use before and after playing for enhanced string life". I did it for a while, but I just couldn't be bothered in the end. Thats most likely just my lazyness, but considering they say its a polymer coating that binds itself to the string or whatever, I was expecting something different. I cannot say I have really noticed a big difference in string life either, from the amount I have applied so far.
