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 DEWALT DCS331B stands apart from every other jig saw in this group by sheer owner scale. With 7,970 reviews at a 4.8-star rating and 600 units purchased last month, it is the clearest best-seller in the category. No other saw in this batch comes close in buyer volume or review depth.
It runs on a 20-volt battery at 3000 RPM, weighs 5.6 pounds, and uses a carbon steel body. Dimensions are 11.25 inches long by 11 inches wide by 3.9 inches high, keeping it compact for a full-featured cordless tool. At $129.00 it undercuts the corded BOSCH JS470E by $30 while offering the freedom to cut without a cord.
The battery is not included, which adds to the cost for new DEWALT users. But for the large base of tradespeople and DIYers already on the 20V MAX platform, the DCS331B at $129 represents exceptional value relative to its review-backed reputation.

How does 3000 RPM compare to corded jig saws in this group?
