The Barrel CRID detector has been operating successfully at SLD for the past seven years. It is an important tool for SLD physics analyses. We report results based on long term operational experience of a number of important quantities such as the Cherenkov quality factor, No, of the device, fluid transparency, electron lifetime, single electron detection efficiency, anode wire ageing, TMAE purity, long term stability of the gas refraction index, liquid radiator transparency, Cherenkov angle resolution and the number of photoelectrons observed per ring.
