All three use Directed Force lie-angle balance to eliminate face rotation. The difference is shape, aesthetics, and who each putter is built for. Which one fits your game?
Quick verdict
All three are excellent putters that eliminate face rotation. The DF3 ($389) is the best performer and the best value — buy it if you can accept the unconventional look. The OZ.1i ($449) is for golfers who want L.A.B. technology in a more conventional mallet shape. The Mezz1 Max ($449) is the compact option for golfers who dislike oversized mallet heads.
L.A.B. Golf
The original Directed Force design. Maximum lie-angle balance technology in the most performance-focused shape L.A.B. makes.
L.A.B. Golf
Same Directed Force technology in a more conventional mallet shape. Sleeker profile with the best alignment aids in the L.A.B. lineup.
L.A.B. Golf
Directed Force in the smallest head. A compact mid-mallet for golfers who want lie-angle balance without the oversized profile.

DF3
OZ.1i
Mezz1 Max
The most unconventional head in the lineup. The original Directed Force design polarizes golfers at address — you either embrace the unusual shape or it throws off your confidence.
Sleeker mallet profile that reads more mainstream. Still distinctly L.A.B., but the cleaner lines make it easier to love at address than the DF3.
Closest to a traditional mid-mallet. Compact, refined, and the most visually approachable putter in the L.A.B. range. Blade-leaning golfers will appreciate the smaller footprint.
DF3
OZ.1i
Mezz1 Max
The larger head provides the most noticeable stability feedback through the entire stroke. You can genuinely feel the lie-angle balance keeping the face square — it's the most tactile expression of the technology.
Refined and confident through impact. The mallet shape dampens vibrations slightly more than the DF3, producing a softer, more controlled feel that many golfers prefer.
Compact head means less mass behind the ball and slightly less tactile feedback. Still solid, but the smaller profile trades some of the 'locked-in' sensation the bigger L.A.B. heads deliver.
DF3
OZ.1i
Mezz1 Max
The unconventional shape takes a few rounds to read confidently at address. Once you adjust, alignment is fine — but the learning curve is real, especially coming from a traditional putter.
The mallet profile provides the best visual alignment in the L.A.B. lineup. Clean sight lines, symmetrical shape, and a natural frame for the ball. Easiest to aim consistently.
Compact with decent sight lines, but the smaller head offers less visual guidance than the OZ.1i. Better-suited for golfers who align by feel rather than visual cues.
DF3
OZ.1i
Mezz1 Max
All three eliminate face rotation through Directed Force, but the DF3's larger head provides the highest MOI. Off-center strikes hold their line better here than on any other putter in the lineup.
Close behind the DF3. The mallet shape distributes weight effectively, and the lie-angle balance means mishits still track. A marginal step down from the DF3 on pure forgiveness.
Trades some stability for compactness. Still far more forgiving than any traditional putter thanks to Directed Force, but the smaller head means less MOI on heel-toe misses.
DF3
OZ.1i
Mezz1 Max
Distance control is excellent thanks to Directed Force keeping the face square through impact. Consistent energy transfer across the face, especially on lag putts where stability matters most.
Matches the DF3 on distance control. The mallet shape provides a stable, pendulum-like stroke that produces repeatable speeds. Forum users report immediate improvement on 20-30 footers.
Good distance control but slightly less consistent at longer distances due to the smaller head. Inside 15 feet it's equal to its siblings; outside that range the reduced MOI shows.
DF3
OZ.1i
Mezz1 Max
Forum users consistently report the DF3 produces the purest roll in the L.A.B. lineup. The face stays perfectly square through impact, launching the ball on its intended line with minimal skid.
Very close to the DF3 on roll quality. The slightly different face geometry produces a marginally softer launch, but the ball still gets rolling cleanly and tracks true.
Good roll quality, but the compact face gives less margin for imperfect strikes. Center hits roll beautifully; off-center contact produces slightly more variability than the larger heads.
DF3
OZ.1i
Mezz1 Max
At $389, the DF3 delivers the best performance in the lineup at the lowest price. Dollar for dollar, it's the best-performing putter L.A.B. makes — the unconventional look is the only reason it costs less.
At $449, you're paying a $60 premium over the DF3 for a more conventional shape. The performance is marginally lower across most categories. Worth it if aesthetics matter to you — but the data says the DF3 does more for less.
At $449 — the same price as the OZ.1i — you get the least forgiving and lowest-performing putter of the three. You're paying for compactness. Fair trade for golfers who need it, but objectively the weakest value.

This comparison is unusual because all three putters share the same core technology. Directed Force lie-angle balance — L.A.B.'s patented system that eliminates face rotation during the stroke — is identical across the DF3, OZ.1i, and Mezz1 Max. The engineering that makes these putters special is the same in each one.
So the differences come down entirely to head shape, visual preference, and the physics of head size. The DF3 is the purest expression of the technology — the largest head, the highest MOI, the most stability. It's also the most unconventional-looking putter in golf. L.A.B. priced it at $389 because they know the aesthetics limit its audience, not because it's a lesser product. In fact, it's the best performer of the three.
The OZ.1i packages the same technology for mainstream tastes. It looks like a proper mallet, aligns like a proper mallet, and rolls like a L.A.B. putter. At $449, you're paying a $60 premium for a shape that won't raise eyebrows on the practice green. For many golfers, that's money well spent — confidence at address is worth more than a tenth of a point on a review score.
The Mezz1 Max exists for a specific golfer: someone who grew up playing blades or compact mallets and physically cannot get comfortable behind a large putter head. It shrinks Directed Force into the smallest package L.A.B. offers. You give up some forgiveness and stability — that's the unavoidable physics of a smaller head — but you gain a putter that feels familiar while still eliminating the face rotation that plagues traditional designs.
The question isn't which technology is best — they're the same. It's which shape fits your eye and your stroke. If you can get past the look, buy the DF3. If you can't, the OZ.1i is the obvious answer. And if neither mallet shape works for you, the Mezz1 Max is the bridge between L.A.B.'s innovation and the compact putter world.

DF3 — our take
The L.A.B. putter to beat. Best performance, best value at $389. The unconventional look is the only barrier — and once you get past it, the results speak for themselves.
Best for: golfers who prioritize performance above all else
OZ.1i — our take
The easiest L.A.B. to love. Same zero-torque technology in a shape that actually looks normal at address. Worth the $60 premium if the DF3's aesthetics are a dealbreaker.
Best for: golfers who want L.A.B. tech without the visual leap
Mezz1 Max — our take
The specialist's choice. Compact, precise, and still lie-angle balanced. Not as forgiving as its siblings, but the perfect bridge for blade-leaning golfers who want L.A.B.'s consistency gains.
Best for: low handicappers who prefer smaller putter heads
