My contour ascensia meter tested 10 points lower than the Alphatrak and doesn't require any kind of settings/adjustments. So, I don't need the Alphatrak, this one does exactly what is needed and costs less than $30 for the meter; strips are $50-$55 joclyn candle site: http://www.gratefulness.org/candles/candles.cfm?l=eng&gi=fert [Posted in FML 7908]
