Found out my LG phone won't work with the OTG camera deal. Did get the laptop to pay attention with a trial version of Winzip to decompress the file, messaged the seller and got a link to the file that works, actually works pretty darn good too. Seems to have auto focus and light control, really inspected my teeth so far. Hard to believe 13 bucks. 150 psi on a stocker is fine with all 8 fairly equal.
