Hi there,
Yea, so I have had bords made , but not assembled. Very good product.
I wanted to try a roll your own end-to-end So I setup with EasyEDA and in it you can go from Schematic to PCB to built units delivered in about a week if not to complex.
They use JLCPCB as the board house with easyeda, but all the files export and import into seeeds Fusion PCB service. They are more familiar and I had to chase down some hard to solder parts to make one project happen. It is amazing what you can do TODAY!
---- At BlackBox Data Communications Co. the Catalog folks, We had a floor of engineers and cad guys and wave solder machines, but it still took months to get anything in solder and then , test and then reviewed and approved and FCC’d and YOI…
Today takes about 7 days and you holding it in your hand ready to program. Unless of course you provide the code to flash to the parts.
either way you can’t go wrong. The DRC in the cad and there online support with your order it’s almost too easy. 
Definitely give them a run.
