Got my PRD18-14DN2 in and tested with the original thicker wall drop tuber that gave me issues with the other sensors for brass.. Works like a champ even with jiggling. So indeed not all sensors are created equal and the PRD18-14DN2 is truly the better one out there. One handy bit with the induction sensors is being able to quickly power them from a bench supply and quickly test them out. I am a convert now!
