Converted a D800 and the compact flash slot stopped working. Due to travel I was unable to ship it for repairs before the warranty ran out. I had lengthy communication prior to the trip and was NEVER told not to use the camera. Upon my return they said I may have damaged the camera and they wouldn't stand behind the conversion. The SD slot works but the compact flash doesn't. They never offered to even take a look but played a game of trying to blame me for a problem they created. More amazing to me is they never ever tested the cameras functionality prior to returning it to me. I wouldn't go near a company that is so unscrupulous. Keep away. There are other companies doing conversions that don't slam the door on their own faulty workmanship.
