## What reviewers found

### Bambu Lab H2S

- CGMagazine (8/10): Called it refined and reliable. Real world print times were about 20 to 30% shorter than typical fast CoreXY profiles and aggregated XY error measured under 0.5 mm. Multi color prints ran a few hours longer than on the H2D on day long jobs, with considerable purge waste. [Source](https://www.cgmagonline.com/review/hardware/bambu-lab-h2s-3d-printer)
- The Gadgeteer: Ran the H2S AMS 2 Pro combo for about a month, often around the clock. First calibration took about 30 minutes, PETG CF prints finished well and the AMS 2 Pro was nearly error free. Downsides were purge waste on multi color jobs and the pricey optional Vision Encoder. [Source](https://the-gadgeteer.com/?p=485726)

### Bambu Lab P1S

- Tom's Hardware: Said it hits a sweet spot with affordable CoreXY speed, an enclosure for high temperature printing and simple auto leveling. Downsides were noise, proprietary parts and AMS filament waste. [Source](https://www.tomshardware.com/reviews/bambu-lab-p1s)
- All3DP: Printed ASA and PC with little corner warping and found auto bed leveling consistent. Criticized the 720p, 0.5 fps camera and some software limits such as blocked microSD access from the slicer. [Source](https://all3dp.com/1/bambu-lab-p1s-review/)
