He failed to demonstrate the only advantage of this tool which is being able to use power tools with it. He failed to break loose both bolts he attempted with the impact. I know his compressor wasn't on but that's why I said he screwed up the review. If it works with an impact gun than it's great. If it doesn't than it's worthless to me. A long handle flexhead ratchet with a high tooth count will get anywhere this tool can and probably more, including DP's.
