What reviewers found

Anycubic Kobra S1 Combo

TechRadar (4.5/5): Scored 27 of 30 on a print quality test with about 0.21 mm average X/Y error. A 43 minute single color print became a 14 hour multi color print. Source
Notebookcheck: Measured 44 dB(A) at one meter. Quality was best up to about 200 mm/s, and nozzle cleaning plus purging caused significant waste. Source

Elegoo Neptune 4 Max

Tom's Hardware: Speed Benchy took 31 min 12 s. A 250% articulated frog took 10 h 26 min with rough spots and a near layer shift. A TPU purse printed well at 45 mm/s. About twice as fast as the Neptune 3 Max. Source
3DWithUs (4.5 out of 5): Assembly took about 30 minutes. Printed a 520 mm window handle and eight PETG brackets in one batch. The screen failed out of the box and needed a manual fix. ABS warped. Source
