I saw that too lol figures. I did get mine to work Though. Unplugged battery for ten seconds and hold hand a lil above and over the test well I read light can affect that and boomed works like a charm. I love it wish I’d gotten sooner.These are on sale all over the place for Black Friday. I saw one for $89. I used to pay that for refractometers, so for me that is a great deal.
