## What reviewers found

### 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/)

### Flsun T1 Pro

- The Gadgeteer: Called it the fastest printer the reviewer had used; a vase took about 40 minutes. Zero clogs and zero manual leveling across dozens of prints. Loose display ribbon and menus with no back button. [Source](https://the-gadgeteer.com/2024/11/10/flsun-t1-pro-ultra-high-speed-3d-printer-review-breathtakingly-fast-quiet-and-outstanding-print-quality)
- 3DPrint.com: Over 300 hours of printing with no part failures. Measured 71 dB average and 91 dB peaks versus Flsun's 50 dB claim. Parts came out slightly undersized, for example 98.85 mm on a 100 mm Y test, and ABS warped.

- TechRadar (4.5/5): Reviewed the base T1. Scored 29 of 30 in print tests with 0.133 mm average dimensional error. Very loud cooling fan; assembly took about an hour. [Source](https://www.techradar.com/pro/flsun-t1-3d-printer-review)
