I was super anti-Bambu until I started using one..

But after having them for over 6 months (and probably going through 50kg of filament) they are the most hassle-free and reliable printer I've used.

As for fixing them... Parts are super cheap, available, and everything has a video to show you what to do.

I'll take the A1's $9 hot-end replacement over almost any other printer any day
