Works great with one minor exception... the rubber isn't tacky enough to keep the unit in place on my irons. every 10-15 swings I have to adjust the unit pack to parallel with the club face. It doesn't have this problem on any of my graphite shafts, just irons (KBS Tour and KBS hi-rev shafts).
Syncs well with my Garmin S20. Gives instantaneous swing metrics. The metrics make sense; 3 degree out-in with a 5 degree closed face.... power fade..... 2 degree in-out with a flush or close to flush face slight draw.
Helped correct my vicious slice pretty quickly. My swing was way to flat forcing me to come over the top on the down swing causing a nasty out-in swing...... slice.
For $100-150 you can't go wrong, hopefully for the next version they can fix the issue with shaft slipping on irons.
For another $200-400 dollars I'ld like to have some sensors for my hips and shoulders......... one can only wish.
