Double Sided Putting Mirror

Improves:
Alignment
Putter Path
 
Description:
The Double Sided Putting Mirror gives you two training tools in one — eye line and shoulder alignment on one side, putter path and backstroke feedback on the other, so you're not switching between separate mirrors depending on what you're working on.
Flip to the mirrored side to check your eye line, shoulder alignment and ball position at address — if you're set up correctly, your eyes should track directly over the target line. Flip to the black side to groove your putter path and backstroke, using the built-in tee holes for extra visual feedback on your stroke arc.
 
How to use it:
Set the mirror down on a flat section of green or your putting mat with the alignment lines pointing at your target. Take your normal setup and check your eyes, shoulders and ball position against the mirror before you start your stroke. Flip to the black side to work on path — the tee holes give you a physical checkpoint to swing the putter head through without catching the rail.
 
Why it works:
Most putting errors start before the stroke even begins — a misaligned eye line or shoulder line sends the putter on the wrong path before you've hit a single putt. Pairing setup checks with stroke path feedback in one tool means you can diagnose the full picture, not just half of it.
 
Jack's Coach note:
I designed this mirror specifically to fix the two things I see most often in a player's setup and stroke — poor alignment and an inconsistent path. Having both built into one tool means less time swapping training aids and more time getting quality reps in.
