Harvest Tec automatic applicator moisture accuracy

How accurate is the moisture tester on the harvest Tec system? I have a bht-2 moisture meter and it is way off. I know some on here like the bht-2 but I have no faith in mine at all. I would like to get a automatic applicator, but if it's moisture meter is as off as my bht-2 it would be useless to me. Also has harvest Tec ironed out the kinks in the automatic applicator. I have ready bad and good reviews. Also how good does the automatic on option work?
