Update, Link to hotends on Aliexpress here https://s.click.aliexpress.com/e/_c2Jb9Gzx

In this video, I test a few budget high-flow hotends designed for the Bambu Lab P2S 3D printer. These claim to improve flow rate and print speed for a fraction of the official cost — but do they actually perform, or are they just another “buy cheap, buy twice” situation?
