SERUM MANUAL PDF
Started by jh0303
The French manual is not well translated.
I'm sorry to hear that, I don't know any French so I am unable to be of much use there. There are some French youtube tutorials for Serum if that is of any value. If you feel you could do a better job on translation, please don't hesitate to get in touch via the contact form.
Gibt es auch ein Handbuch für Xfer Serum in Deutsch?
Does anyone have the manual in Spanish?
