Yes, they are a class act. I had trouble updating my firmware (mine is one of the earlier units). I had updated it once before, but for some reason it would not update to the new one. They overnighted me an SD card with an update software for me to try and voila, it updated. If that had not worked, they would have shipped me a replacement unit. I have no doubt that if for some reason my Degritter fails to function, they will replace it. Taniel and his team are wonderful!
