I got a screwed up Sigma computer. The screen would fad out and it would stop recording if the temperature dropped below ~45°. I got it taken care of and a whole new computer but they didn't get in a hurry. Took 3 weeks. The place I mailed it to was in I.L. and I called them a few times to see what was going on with it and they would be like " Yeah its right here, we will get to it tomorrow".
