The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, the Atomic DCS571B is the polarizing pick in this pool. protoolreviews.com gives it a high-trust positive verdict for easy one-handed cutting on thinner materials, and Amazon's 4.7 average across more than 7,600 reviews shows broad satisfaction among buyers who picked it for what it actually is, a small saw for plywood, paneling, trim, and quick cuts. The honest counter-signal comes from r/Dewalt threads, where multiple commenters describe blade binding more easily than expected and one calls it the only DeWalt purchase they regretted.
What reviewers liked
- protoolreviews.com endorses it for one-handed cuts on thinner materials
- 4.7 average across 7,644 Amazon reviews indicates broad buyer satisfaction in its intended use
- Lightest format in this pool, well suited to overhead and ladder work
- Brushless motor delivers respectable runtime for the size
Where it falls short
- Multiple r/Dewalt commenters report blade binding more readily than expected
- Community reviewers describe the balance as leggy and battery-dependent
- 4-1/2" blade limits cut depth; not a framing saw
- Reports of regret when buyers expect it to handle hardwood or 2x cuts

The honest counter-signal comes from r/Dewalt threads, where multiple commenters describe blade binding more easily than expected and one calls it the only DeWalt purchase they regretted. Another community thread notes the saw shares motor and housing geometry with DeWalt's angle grinders and feels best balanced with a larger battery. The synthesis: reviewers who buy this expecting a small, agile saw for light material are happy; reviewers who try to push it into 2x framing or hardwood territory are not. Buy it as a complement to a larger saw, not a replacement.

I got the 4 1/2 and it is the only DeWalt purchase I have ever regretted. The blade binds way easier than it feels like it should (say cutting ...
The DCS571B seems like the obvious choice since I'm already invested in the 20v platform. But, I do like the DCS512B for the slightly larger cut ...
