The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Overview
The MARSHALLTOWN 143D is a magnesium masonry float measuring 16 inches long, built with the brand's DuraSoft handle for grip comfort. It's priced at $34.99 and, per the listed dimensions of 16 x 3.13 x 2.9 inches, is sized for covering broad concrete or mortar surfaces rather than tight detail work.
Despite the listed item weight showing as 4 ounces, magnesium is a genuinely light metal, and this float's real draw is its review record: 553 reviews at a 4.6 average, with 100 units bought in the past month. That's the largest review count of any float in this batch, which suggests a long, consistent sales history.
Buyers comparing floats by size should note this is a full 16 inch blade, not a hand-sized detail tool, so it suits broad finishing passes over cramped or detail work.
Pros
4.6 average rating across 553 reviews, the highest review count in this category

Full 16 inch length for covering more surface per pass

Performance notes
A 4.6 average across 553 reviews is a large enough sample to reflect genuine, repeated satisfaction rather than a handful of early impressions, and the 16 inch magnesium blade points to a tool built for covering ground quickly on bigger pours.
What buyers say
