Yes, bambulab is the esayest printer to operate printer out of the box. The M5 needs a litel more expiriance. But since there is a Service center reachable in 5 minutes by car, as well as an 3 year “bring in” guarantee by the seller, Bambulab lost its “easiest printer to use” certificate at least for me.
As long as it runs, yes. Failures are rare, yes. But if… you get it back in operation with a very good wiki that is excellent, this is beyond all doubt and was done very, very well. But to get it back in operation takes longer than average and became much more complicated… so for sure there are now easier to use printers out there, it`s just dependet on the view you take.
