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
The Cordless 2438-20 runs on a 12-volt power source at 2800 RPM, giving it enough speed for surface finishing and light paint correction. At 2.3 pounds, it is one of the lighter cordless polishers in this category, which reduces arm fatigue when working overhead or in tight spaces.
Based on specs and verified owner reviews, the 4.6-star average from 853 buyers reflects consistent satisfaction with the tool's ease of use and portability. The cordless design removes the overhead of managing a power cord across a vehicle hood or door panel, which is a real practical advantage for DIY detailing sessions.
At $159.99, the Cordless 2438-20 sits in the accessible mid-range for cordless polishers. Buyers who prioritize low weight and freedom of movement over raw power output will find this a straightforward choice. The 12-volt platform does limit output compared to 18V or 20V options, so it is best matched to finishing and maintenance polishing rather than aggressive paint cutting.
