Laser power and work area7.0/10

Software and control7.0/10
Own PC software and app, LightBurn and LaserGRBL, USB or Wi-Fi without an account, Windows, macOS and phone apps give 4 of 5; no camera.
Price and total cost5.0/10
$369 machine-only against a $649.98 reference with free shipping over $50; air assist ($449 bundle) and an enclosure ($489 bundle) are needed for cutting and fume safety.

Claims we checked

The published claim, then what we found. Live statuses. How we review

The claim

20W laser

What we found

Fine print

Maker and Amazon listings call 20 W the output power (20000 mW) with about 120 W input. One review site notes older AtomStack '20W' figures meant electrical draw; a test of the older A20 Pro measured 20 W optical.

Source · checked Nov 14, 2026

The claim

Flame detection

What we found

Fine print

Page lists flame detection, but it requires the separate Z2 Z-axis slider; machine-only does not include it.

Source · checked Nov 14, 2026

The claim

Air assist

What we found

Contradicted

Review sites disagree, and the product page sells air assist in a $449 bundle against $369 machine-only, so the base machine does not include it.

Source · checked Nov 14, 2026

The claim

12 months warranty and free shipping over $50

What we found

Verified

Store banner and product page state 12 Months Warranty and free shipping over $50.
