I have not noticed any longer travel time on parts that I have ordered from China.

However the last package was sent in record time, It left China in the same amount of time Though It flew thru customs here in record time.
This could be because lots are not ordering from China, Spray the package and its contents with antiviral disinfectant then let dry before use.

Remember to dispose of the packaging disinfect then wash hands and wait for it to dry before plugging it in and testing it.

I lot a 3D Printer firmware's has extruder lock's at temperatures under 170C, My 1st 3D Printer extruder was turning backwards.
I rewired to turn the correct direction, it however was a used 3D Printer so it could have been the original owners mistake.
