@Elder1945 how is the connectivity working out for you lately?
I'm Receiving my new unit after mine bricked over the weekend tomorrow and come to the crossroads of continuing the upgrade or just returning the new unit. I need reliability because I work long hours and the classic hasn't failed me yet; all my probes have been super reliable too and the difference in the probe reading from your refractometer concerns me.
That being said: Neptune has a+ customer service trying to get this product out to us in working order. I realize it may just be software and I'm excited to progress with the new unit. My programming was so involved so I'm a little worried about the crossover too :/
