StuartL,
There is no P in the serial number of my S18. Are you aware that all of these machines come China? My machine did not come from AliExpress. Please do the euc world a service and post links the source of your information with more details of your concerns. It would help us all. I’m guessing you are a concerned citizen, not an actual buyer of an S18. If you are in fact a buyer, please post your intentions.
