L.A.B. Golf OZ.1i Putter
MyGolfSpy's top-ranked zero-torque putter for 2025 with the best PuttView Handicap of any category winner — a high-MOI mallet with a stainless steel insert that finally makes Lie Angle Balance technology look conventional.
The consensus
The L.A.B. Golf OZ.1i is the putter that finally brings Lie Angle Balance technology to the mainstream. Developed in part with Adam Scott, the half-moon mallet shape looks more like a conventional putter than any previous LAB model, while the 303 stainless steel face insert — a LAB first — provides the firmer, faster feel that traditional putter users expect. In MyGolfSpy's 2025 Most Wanted putter test, the OZ.1i posted a PuttView Handicap of -7.6 — the strongest scoring performance of any category winner, beating the top blade, the top mallet, and every other zero-torque putter tested. It was the top performer on short putts and finished inside the top three on long putts, with a best-in-class average leave distance of 0.59 feet.
Where sources agree: the technology works, the insert is a meaningful upgrade, and the shape is finally accessible. Plugged In Golf found that hitting your intended line becomes automatic once you stop trying to manipulate the putter, and GolfWRX member testers called the stainless insert 'a HUGE improvement' over previous aluminum-face LAB models. Golf Monthly rated it 4.9 out of 5 and praised how the half-moon body sits beautifully behind the ball, calling it the LAB putter that may finally tempt skeptics into trying zero-torque technology. Golf Digest placed the OZ.1i on its 2025 Hot List as a Top 5 performer for low handicaps, and Independent Golf Reviews called it 'the hottest putter in golf' — not just in popularity, but on the greens.
Where the honest trade-offs remain: the adaptation period, the fitting requirement, and the price. Zero-torque putting requires 1-3 weeks to fully adapt, and the putter must be properly fitted to work as intended — this is not a grab-it-off-the-rack purchase. At $499 for the stock model and $599+ for custom builds, the OZ.1i is premium-priced with longer lead times than major OEM competitors. The technology specifically addresses grip-tension-related putting problems; golfers whose issues stem from path mechanics or green reading may not see improvement. But for the player willing to commit — especially one who suspects grip tension is costing strokes — the OZ.1i has the strongest data-backed case of any putter on the market in 2025.
