## What reviewers found

### Bambu Lab A1

- Tom's Hardware (Editor's Choice): Called it a reliable and quiet high speed printer at a competitive price. A speed Benchy took 19 min 15 s, and a panda print took 2 h 40 min in one color versus 6 h 46 min in three colors. [Source](https://tomshardware.com/3d-printing/bambu-lab-a1-review)
- TechRadar (Editor's Choice): Scored 29 of 30 in its print quality test with a combined dimensional error of 0.099 mm. Flagged the software as complex for beginners and the open frame as a limit for ABS and PC. [Source](https://www.techradar.com/pro/bambu-labs-a1-review)

### 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](https://www.tomshardware.com/3d-printing/elegoo-neptune-4-max-review)
- 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](https://3dwithus.com/elegoo-neptune-4-max-review-3d-printer-testing-settings-tips)
