I have one and it held up well last season for me without issue. I have the 6" model and it tears through ice and it doesn't suck battery with my Dewalt drill. I previously had an extension for another auger and it transferred without issue to the Nordic Legend. They are shipped by HT Industries so like hardwater stated, it is basically the same thing. I also don't use the disc that it came with and instead use the Ice Master adapter, but that's just personal preference.
