The GoSports putting mirror is a genuine feedback tool for the part of putting you can’t feel: your setup. Lay it on the green, settle over the ball, and it shows you at a glance whether your eyes are over the ball and your shoulders are square — two faults that quietly ruin more putts than a bad stroke does. It’s cheap, it passes our feedback test, and it earns its place among the aids that actually work. Here’s the honest account.
What it is
A flat, portable putting mirror with reference lines and slots for tee gates. You place it on the carpet or the practice green and set up over a marked spot; the mirror reflects your eyes and shoulders so you can see, not guess, where they are, and the tee gates train a repeatable stroke path back and through. It works indoors, which is where most putting practice actually happens. Those are the maker’s intended uses; our scoring method is in how we rank.
Where it shines
Exposing setup faults you can’t feel. Almost every amateur believes their eyes are over the ball and their shoulders are square; the mirror is often the first honest evidence that they’re not. Because eye-line and shoulder alignment dictate where you actually aim the putter and which way the stroke travels, fixing them can straighten your start line without changing anything about the stroke itself. The tee gates add a path check on top. It’s the cheapest way to make the invisible visible in the setup, and that’s exactly the kind of immediate feedback we rank highly.
Where it stops
It fixes setup and short-stroke path — not pace, and not green reading. The mirror sharpens your aim and start line on short putts, but it does nothing for the distance control that causes most three-putts from range, and it can’t teach you to read a break. It’s a setup tool, and a good one, but a complete putting practice needs a pace drill alongside it. Pair it with the pace feedback of a PuttOutand you cover most of the short game — we compare the two directly in PuttOut vs the GoSports mirror.
Branded mirror or any mirror?
As with alignment sticks, the drills matter more than the brand — a slightly different mirror layout won’t change your results. What you’re buying is a durable, portable mirror with sensible reference lines and gate slots at a low price. The GoSports does that job well; don’t overthink the specific model.
Who should buy one
Anyone who misses short putts to one side and can’t work out why — the answer is usually aim or eye-line, and the mirror shows it. It’s a cheap, honest setup fix that works on the living-room carpet. If your putting problem is distance control on long putts, start elsewhere: the mirror won’t help pace, and a pace-feedback tool will.
