My experiences with Fuji's service have been nothing but excellent. I have two X-T1 cameras (Black and Graphite Silver.) G.S.' SD Card Compartment door got really loose and the Black's Connector Compartment door was warping. Sent the GS to their Edison (NJ) service facility; only took a week from the time I sent in and received it back. The Black was sent in yesterday.
About ten months or so ago, my X100s after firmware update started introducing horizontal bands when used with film simulations (jpegs) at smaller apertures. The camera had been out of warranty for a few months then and Fuji service was going to charge me; I think they quoted me $185. The next day I got a response to my first email I had sent to tech support that requested me to call them. The person I spoke with worked in QA. He asked me to not send the camera to Service, instead send it to his unit; apparently for testing. They offered me a X100T as replacement. Arrived next day via Overnight. When I opened the box it included the X100T camera, tele and wide attachments, hood, thumb rest and soft shutter release, an extra battery, and the leather case with strap. Everything black instead of silver but brand-new! Made me very happy.
Cheers.
