Professional reviewers praise the DeWalt DCS391B for its speed and portability, noting it is a top performer for maneuverability in light-to-medium tasks. However, experts consistently note that it is outpaced by brushless upgrades and recommend those models for professionals requiring sustained power and efficiency.
Everyday users appreciate the saw's lightweight nature and quick setup for DIY projects like decking and shelving, often praising its smooth performance on standard lumber. Common complaints focus on the lack of modern features like brakes or lights, shorter battery life, and occasional blade binding in dense wood.
Professional reviewers like TechGearLab and iFixit highlight the BDCCS20B as an excellent lightweight trim saw or handsaw replacement for DIY enthusiasts. They praise its compact design, pivoting shoe, and variable-speed trigger for enhancing control and versatility in small projects. However, critics consistently note that the underpowered motor and short battery life limit its utility for broader or more demanding applications.
Everyday consumers generally find the saw to be great for consumer use around the house, particularly for cutting shelves and trim. The light weight and battery interchangeability are frequently cited as major advantages. However, recurring complaints focus on the power limitations for anything beyond modest tasks, with users noting it is not suitable for major construction work.
