Great for prototyping and small manufacturing runs
I've been using these guys for prototyping as well as low volume assembly and manufacture for years now, and the consistency and quality have always been spot on. Assembly and panelling of awkward boards (components raised on their legs without spacers, non-standard insertion of pins though the board etc.) wasn't ever a problem, and blank PCBs are always well produced and good quality. Sure, you can get finer resolution silkscreening elsewhere, but you also pay far more at those board houses, and the quality from PCBWay is more than adequate at the price. Plenty of shipping options too that allow you to avoid expensive couriers if you're not in a hurry, and fast shipping if you are, though the cost reflects the perhaps surprising weight of PCBs in bulk. Communication is always prompt, and while it can sometimes suffer a little from the language barrier, it's never actually a problem and confirmations are sought from the customer when things aren't 100% clear. Price quotes for more complex jobs aren't always 100% accurate until they're reviewed and it's time to pay, but you do always have the final figure before you actually make the payment - there are no additional or hidden fees, and the cost changes (which, to be fair, as often go down as they do up) are down to them rearranging the panelling to suit assembly, and to passing on the actual cost of parts from Farnell, Digi-Key or whoever to be assembled directly onto the customer.
