I recently used PCBway for the first time. Had issues with the paypal screen timing out, but was told I could just send the payment direct. There was an extra £16 to pay from DHL, which apparently is a DHL thing (seen the '£16' value mentioned a lot for different items) its not PCBway that charge this or make money form it. The shipping was indeed by far the biggest cost but.. - it took 4 days between uploading my gerbers, and having the boards in my hands. £40 for 10 boards (I needed 5 immediately, another few for future orders) in 4 days.
I cannot say I have used many chinese PCB companies, or ordered very large quantities, but frankly with a 5-day lead time, the same boards would have cost upwards of £150 from a UK company that does fast prototype service. The PCB quality is excellent, the best I've seen. I don' see how it can be a 'scam' because as far as I could tell, PCBway only use either standard international shipping, or DHL, and DHL *always* costs a lot. They may add a fee on top of this but the boards have to be packed, boxed, and labelled - thats not the couriers job.
So, four days to be manufactured, tested, packed, and shipped form the other side of the world for £40. Also, as the bulk of the cost was in US dollars, the sterling is pretty weak at the moment, so before the silly 'brexit' it would have been about £32. Thats £3.20 a board, for 4 days.
So aside from a hiccup with the paypal process - wheres the scam? What were you charged, and for what, and how long did it take? I'll admit I didn't like the sudden 'oh btw, you also need to pay £16' I got from DHL via SMS, but that isn't PCBways fault. And it was more just 'unexpected' than 'scam!!', it's still very cheap for the time and quality - I can actually afford to make the ~230 odd projects I've designed over the years that didn't warrant the cost of a custom board.
Ok, this is starting to sound like a review but you can't just say '<company> scammers!' without any details and expect a rallying cry to your cause.
