I have maybe a few hundred prints on Bambu Labs printers, and I've had fewer than 20 failures, pretty much all from bad design choices on my part. They have been quick, reliable workhorses that just spit out the parts I need.

I did have an issue with one of them having a warped bed, which caused bad adhesion on several prints, but I contacted support, they walked me through some debugging, then just sent me a new one. It seems that early on they had a manufacturer that was putting out warped beds that weren't caught in QC, but they've dropped the manufacturer. Maybe you got one of these warped beds as well? You can diagnose that with a straightedge, a ruler, and a flashlight.
