I have the Dirt Tricks unit and am happy with it. I installed it with the bike lying down as advised, and after some use, I pulled it out (with bike lying down) to ensure the unit wasnt fully extended - was all good. I did notice I shaved a piece off the rubber washer that goes on the unit, when I tightened it down - top of the CCT leaked a little oil, so I orderred another rubber washer and a spare for later if I check its extension again.
