I just got up and running a few days ago with mine. I have yet to get enough CL to be generated that shows up in my test. I set it to 60% intially per the instructions and only detect a very light pink color in the Taylor CL test. I just bumped it up last night to run at 100% and will test again tonight.
Did you have it calibrated yet? My PB hasn't done this yet but says he will since the factory calibration is usually way off according to him.
