I own a Storm Strong Arm Plus and I will agree that it is comfortable, very easy to put on and take off between frames, and produces excellent revs. Although I don't mess with the adjustable settings, I've never experienced any problems with the locking dial when I did try to use other settings when I first got it. I heard the second generation Strong Arms had an improved locking feature. Maybe this is the one I have? I previously used an original Cobra brace, but never tried the Robby's Rev brand. After using the Storm brace for most of this season, I would recommend it to someone looking to add some revs to your game.
