The Second Opinion — Putting Alignment Mirror

The mirror doesn't flatter. That's why it works.

Why it's here: eye line, shoulder line, putter face: the three things you can't see while you're doing them, on one slab of acrylic. Two minutes on it before a round is worth more than forty aimless putts on the practice green. Tour players carry one; theirs just costs four times more.

The caveat: it's acrylic, not glass. Fine in a bag pocket, unkind under a golf shoe.

• Guides: eye line, face alignment, stroke path
• Material: printed acrylic mirror
• Fits: standard bag pocket
