Genuine Apple Mini Display Port to DVI - FAIL = Poor Value for your $

Last year I bought a 3rd party mini display port to dvi adapter this failed after 3 months - So I then purchased the genuine Apple branded cable - 5 months on this cable has failed.
If the Apple one which cost me about $30 only lasted for 5 months and the non genuine $3 eBay special lasted me 3 months the genuine Apple one seems pretty poor value for the price.
My solution - just ordered a lot of 10 cheapos off eBay for the cost of 1 genuine cable.

Why are these cables failing..... Has anyone else had a simular experience with this product?
