It's not from Fasttech...
The company name they use on their shipping labels is Cloud Commerce Systems.
If you can't determine why it came to you... consider it your lucky day and go buy a Lottery Ticket before it wears off!!
BFE Corporation as return address on that envelope...That is definitely NOT from Fasttech....that is not their city, address, or company...some other Chinese company got your name and address etc if you are "Michael T" as shown on the address..otherwise the PO screwed up and most likley gave you somebodys else's order ..
All I know is talking to a US distributor, if you are registered or they get your address he said they wont leave you alone. And it could be like hey here's some free stuff buy from us! Its the only thing I can think of. Since this hardware selling clones, ejuice, every vaping thing you can think of is blowing up like the ".com" era.
BTW if no one knows the short cut to zoom in. Hold ctrl and mouse wheel up and down.
And if you don't have a mouse-wheel hit CTRL and + to zoom in, CTRL and - to zoom out.
As others have said, definitely not fasttech...
EDIT - good post by szot - interesting. From the link posted, I'd be very wary of 'little black dots' coming in the mail from anywhere. Now tools, they're always welcome to send those to me...
