Last year I said I'd probably never recommend another Bambu Lab printer again.
I still use my P1S, but after Bambu Lab started pushing their always-connected cloud solution as the new default:
I blocked the printer from the Internet via my OPNsense Firewall I stopped updating the firmware I locked the printer into Developer mode I deleted Bambu Studio and started using OrcaSlicer I had to do that to keep it under my control, instead of Bambu's.
The bulk deals at Bambu were pretty inline price wise with china filament- I was getting it under $14 a kilo. and I do like their refillable spools reducing overall waste and taking up way less storage space in my cabinet. But yeah none of that’s worth it at this point, and their bulk deals are all mostly gone.
I mostly use Sunlu at ~$10/spool. Also refillable.
