	Name	Purchased for ($)	Link	Made In
	Starrett	$144.00	Search on Amazon	Scotland
Best overall. Perfect at every position on the 1-2-3 block, tied for second in slide consistency at 36 g of variance, and third-smoothest feel — but no absolute linear scale.
	Fowler	$120.00	Search on Amazon	China
Tied for second overall, with the closest O-ring groove measurement at 0.310 in, an absolute linear scale, and a long-life CR2032 battery.
	Mitutoyo	$250.00	Search on Amazon	Japan
The smoothest-feeling caliper tested, with an absolute linear scale, over-speed error elimination, and patented low-power circuitry. Tied for second overall.
	Werka	$27.00	Search on Amazon	China
The value standout: tied the Starrett for second place in slide-force consistency at 36 g of variance, missed a perfect gauge-block score by 0.0005 in, and auto-powers down when idle.
	INSIZE	$72.00	Search on Amazon	China
The consistency champ: the steadiest beam in the lineup at just 28 g of slide-force variance, and the only caliper to land exactly on target at all three depth measurements.
	Neiko	$25.00	Search on Amazon	China
Extra-large LCD, 0.0005 in resolution, and the second-smoothest feel in the entire lineup — the most consistent slide of the budget brands, peaking around 390 g.
	Hardell	$23.00	Search on Amazon	China
One of only two calipers with perfect readings at every position on the 1-2-3 block, and it ships with a bonus ruler. Depth accuracy trailed the field, though.
	Kynup	$20.00	Search on Amazon	China
Stainless steel with IP54 splash protection and a long-life CR2032 battery. One of the smoothest budget sets, holding a narrow 309-350 g force band across the travel range.
	Quinn	$50.00	Search on Amazon	China
Harbor Freight's upmarket option and the least expensive caliper with an absolute linear scale, so it never needs re-zeroing at power-up. The slide is the tightest tested, spiking past 500 g.
	Vinca	$21.00	Search on Amazon	China
Fine-polished stainless steel that tied for second in depth accuracy at just 0.0015 in of total discrepancy, though the slide has a stiff spot reaching about 450 g of force.
	Jiavarry (Simhevn)	$18.00	Search on Amazon	China
The first in the lineup with a thumb wheel, plus a battery-change screwdriver and two spare batteries. Sharp outside tips made it second-closest on the O-ring groove at 0.3115 in.
	S&F	$40.00	Search on Amazon	China
The heaviest set at 206.09 g with a CR2032 battery and third place on the groove test at 0.3125 in — but the only caliper that would not consistently return to zero.
	Johnson Level & Tool	$36.00	Search on Amazon	China
Tied for second in depth accuracy with just 0.0015 in of total discrepancy, though its wide outside tips left it well short on the O-ring groove at 0.3295 in.
	Louisware	$26.00	Search on Amazon	China
Nearly perfect on the gauge block (0.0005 in cumulative error), but the beam alternates between stiff and loose spots, and wide outside tips overshot the groove at 0.336 in.
	Pittsburgh	$10.00	Search on Amazon	China
Harbor Freight's composite-bodied entry at 57.36 g. Rough sliding feel, but it settled into roughly a 20 g force variance after an initial spike, and it isn't designed for depth measurement.
	Adoric	$7.00	Search on Amazon	China
The lightest set at 54.33 g, with an auto-off after 5 minutes and a spare battery included. The display shows only two decimal places, and the slide feels gritty.
