The ifrothgolf review
A solid, curved plastic guide you set down beside your ball. You rest the heel (or toe) of the putter against the inside edge and stroke back and through, letting the curve teach your hands the gently arcing path that a square-faced stroke naturally wants to follow. The T3 is the travel version: short, light, and bag-friendly, so it earns a place in your practice bag rather than living in the garage. No batteries, no app, no setup beyond placing it on a flat surface.
What's great
The feedback is instant and physical. You feel immediately when you drag the putter straight back or loop it outside the line, because the head bumps the guide. That tactile correction sticks faster than staring at a video of your stroke. It is genuinely portable, holds up to abuse, and works on a kitchen carpet as well as the putting green. For ingraining one specific thing, a consistent stroke path, it is about as direct a tool as exists.
Worth knowing
It only trains path, not face control, distance, green reading, or whether you actually start the ball on line, so it is not a complete putting fix. Purists who believe in a straight-back-straight-through method will find the arc philosophy actively unhelpful for them. The 21 inch T3 is short, so it only covers the stroke length of shorter putts; longer lag strokes run off the end. And the bare plastic can slide on slick surfaces unless you sit it on the supplied grip discs or a mat. At around GBP 49 for the travel size it is also not cheap for a moulded guide.
The verdict
A focused, well-made tool that does one job, grooving a repeatable arcing stroke, better than gimmickier gadgets. Worth it if a wandering putter path is your actual problem and you will put in the reps. If your misses are about speed or face angle, your money is better spent elsewhere.
