The HackMotion is an impressive piece of technology that offers unparalleled feedback on wrist angles, but its high price and rigid coaching logic make it better as a supplement to professional lessons rather than a replacement.
Their scorecard
Wrist Flexion: helps/5 — Excellent tracking of extension and cupping at the top.
Face Control: partial/5 — Helps by proxy of correcting wrist angles.
Rotation: partial/5 — Measures azimuth angle to track swing plane.
What they rate
Extremely lightweight and doesn't interfere with the swing
Triggering multiple senses (sight, sound, feel) aids the learning process
Simple setup and fast calibration
What they don’t
The Pro version at £855 is difficult to justify for most players
The app suggests 'perfect' positions that may not suit every unique swing
Instructional phrasing can be awkward
