Their services are top notch, but communication with them is FRUSTATINGLY SLOW. It takes entire days or weeks to just clarify some custom details about a board such as dielectric material, or to clear up some details about BOM. While their prices and board fabrication/assembly services are extremely good, they seriously need, please for the love of god, to hire personal for their support team. I lost many deadlines on multiple projects because they take ages to just get an order approved
