I met the INVENTOR of this gadget last month while in China. I was there for the world's second largest trade show CIPS (China International Pet Show) and this inventor was sharing a booth with a friend of mine
Side note, its NOT Chinese, its Taiwanese. The Taiwanese quality standard is near and sometimes surpasses US quality on their goods.
Unfortunately for Taiwan, they are an independent country with their own military, government and strong economy but US still won't recognize them as a true country (thats another subject)
Anyways, the inventor has been working on this unit for years, supposedly near fail proof. While talking to the guy for 20+ mins, I got to hold the unit, check out the features and see how the data is inputted onto a nearby computer.
The inventor said that Neptune Sys. wanted his tech, patent rights and exclusiveness for their controller but he refused their terms. I'll leave it at that for y'all to speculate why.
I do believe that there is enough cost in R&D, software, and quality material to justify the $1K+ retail price tag. But there is so much things myself and 95% of us here can do with that much money versus knowing how our Alk level is every 30-45 mins.
So I'm gonna settle with my Salifert alk test that has been pretty solid for me all these years.
For the deep pocket baller, frag-star-millionare farmers and coral wholesalers this unit could be worth it.
