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

Context, not marks against it, and our read of the data, not a lab test.
Overview
Among all impact drivers in this category, the DEWALT DCF870B pairs the highest price tier ($178.08) with the credibility of 1,000 monthly purchases and 726 owner reviews at 4.7 stars. That demand pattern signals a tool that tradespeople and serious DIYers are actively choosing in volume. DEWALT's DCF-series reputation for reliable 20V performance underpins the sales traction, even though the listing does not publish speed, weight, or torque figures.
The absence of detailed specifications in the listing is a notable gap. Buyers comparing the DCF870B directly against the DCF860B ($119.99, 3800 RPM, 2.8 lbs) will find the lower-priced sibling more transparent on specs while still carrying 980 reviews and 1,000 monthly purchases. The DCF870B's $178.08 price implies it may be a newer or higher-spec model in DEWALT's lineup, but that cannot be confirmed from the published data alone.
For buyers who rely on DEWALT's 20V MAX battery compatibility and trust the brand's quality standards, the DCF870B's strong review signals make it a reasonable consideration. Those who prefer to see RPM and weight numbers before committing may find the DCF860B a more transparent alternative at a lower price.

Battery-powered on DEWALT's 20V platform. No RPM, torque, amperage, or weight figures are available in the listing data. The strong sales volume and brand lineage indicate the tool performs to professional standards based on verified owner reviews, but spec-driven comparisons require information not published here.
