Device is already confirmed, but I just wanted to add my thanks to the list of folks who are grateful for this amazingly helpful tool as well as the countless hours you folks have been putting in answering questions and (unfortunately) some repeated questions. Thanks for your incredible work and patience with those of us who are truly noobs at all this.
I was able to get KOReader going and get night vision going! Absolutely astounding. It's far better than I thought it would be! Thanks SOO much. No need for me to look into a different device now.
