End of 2013, 2014, and probably first of 2015 as far as I know, but probably earlier that 2013 I just wasn't associated with them earlier. RVP went from a six blade to a three blade fan. First pn xxxxBxxxx failed quickly they then went to xxxxCxxxx which was better but still failed. They then went to pn xxxxDxxxx and it has been fine, so just make sure they have the D in middle of pn.
