Very good service and communication. Boards are reasonable quality although the silkscreen has been way off mark on the last two orders. Hopefully this will get fixed sometime soon. The competitive price means that I keep on coming back for more silkscreen punishment. (Posted on 9/21/2017)

First time using a PCB service: price, quality and turn-around were excellent. Customer service even flagged a mistake in my order (via clear, prompt emails) and reduced the price. Gerber files sent late Wednesday afternoon, boards arrived (in Adelaide) on Monday. I will definitely be sending all future orders to Elecrow. (Posted on 7/25/2016)

Have ordered many boards from Elecrow now; consistenly fast, low cost and excellent quality. Out of _15 boards of various types (2 layer and 4 layer) I've never noticed a single problem. (Posted on 7/19/2016)
