I've been using PCBWay at work for a while, over 50 designs with 5-20 boards per design ordered. Generally speaking, they aren't the best, but their PCBs are exactly what you'd expect for the price. Sometimes the boards are perfect and only the problem is misaligned overlay layer, which usually isn't a big deal. Sometimes there are visible problems with hole centering and once we received something really unacceptable: [image: Znalezione obrazy dla zapytania pcbway elektroda]
These are 0,5mm holes, so bigger than their specified minimum. The upper board is 4 layer and was probably manufactured in different place (different machine or different plant) than typical 2 layer boards. The lower was meant to be a purely mechanical element (to put pins of a component throught those holes and holes of another, electrical board, push the board to the side and thus make a non-solder socket for it). Fortunately out of 10 boards per design there was at least 1, which was acceptable. Because of these problems, I usually design my boards with 0,3mm traces and spacing and with 0,5mm holes (0,3mm for via stitching ground planes) to avoid problems caused by misalignment. Right now I'm waiting for some boards which use 0,15mm traces and spacing, so I'm going to see if they will turn out OK. But this was only one order from them. Generally, they are OK unless you need a perfect alignment of the layers. Comparing to OSH park, which I used only twice so far - PCBWay is lower quality, but is definitely cheaper. Keep in mind that PCBWay will put a small text on one of overlay layers with order number. They usually try to hide it under components, but sometimes they put it in visible place.

OSHPark is TG170. PCBWay's base offering minimum hole size is .3mm, > this is possibly only relevant (to me) for vias.
