From a professional user: awesome!
This is our second order for a double sided pcb with 0,5mm pitch components. Placed the order on saturday afternoon (europe time) pcb shipped on Monday ... arrived on thursday! A comment on the silk screen: The first order was a very small pcb and we got a good product but not so perfect silk screen. The second order was for more pieces and bigger size the silk screen look perfect! I think they have two different printing process for small quantity prototypes that look fuzzy and production that look very sharp also on 0,9mm text. PCB are very well packed and we found some pieces in excess than ordered.
