      Hi James,

      I never received my Luxi - I just thought I'd mention this in case other backers didn't receive theirs either. Can you look into my order and see what the problem was?


    3. Adam Packard on April 1, 2014

      Just saw the Luxi on my local news here in Utah in their "Fun Finds" segment. You've finally made it!!! :-P

      Seriously though, it was cool to see it. My wife didn't understand why I got so excited about it. :-)

      @V: We're working on the colorimetry functionality, but I can't say exactly when that update will be released at the moment. Stay tuned!

      Hi James. I just saw this KS and realized I backed this. Can I receive the Luxi I should have received for funding this project? How do I go about that process with you?

      Used the app and device today for the first time to pretty good results. Would like to see better documentation on the app and what each function/field is. Any plans for this? Other than that it is a very handy and nice device, thanks.
