I used them, and I was really happy with them at first. My friend then bought me a pair of elixirs for my acoustic (same gauge) and after 3 months I broke a string and went back to d'addario. The strange thing was, my 3 month old elixirs sounded so much brighter and nicer than the brand new d'addario's I just put on.

Never used 'em since, I've stuck to the Elixir.
Real eyes realise real lies.
lol i heard elixirs sound good but break easily unfortunately i cannot use them because my store only carries Daddario and some other german company
