Ernie Ball Paradigm Beefy Slinky 11-54

I have purchased these around mid September because I was curious about other brands of Coated Strings besides Elixir. I have installed them on my Strat and everything seemed to be fine until some hours of practice later when i noticed the strings started to lose their shine in some spots. After a month of playing they are almost rusted and are getting dirty even when using string care products. I am extremely disappointed in this purchase and i'll never try Paradigm or other brands. These are not coated strings, just very stiff, oxidized, blackened, poor strings. I have used Ernie Ball SuperSlinkies that were more durable than these.
