I have used their service for my first ever PCB fabrication.
My first pleasant surprise was the packaging, it is really on a high and professional level. All PCBs came vacum packed- bubble wrapped.
The quality of the pcb is really on a high level.
Pads, traces, holes all are crisp and like on the drawing. Silk screen is also of nice quality. I'd compare their PCBs to PCBs that are used in commercial/ professional products.
I also like their shipping options, and the delivery time is fast.
The customer service is also kind, and they respond back quickly.
I'm happy with the service, I placed another order. I will be using it again, I can recommend Elecrow!
