I have been researching the hell out of this for the last two days and I am really impressed! I also started to crunch some numbers on using my test kits and probe replacement like Salinity, pH and Oxygen and how much do a spend on them per year. I came to the conclusion that the price for the mindstream is certainly more expensive than testing twice a week like I do now, but it is much closer if I was to do daily testing and its a better deal than doing testing two to three times a day and if I look at it from the point of tests happening every 15 minutes. It's insanely cheaper at that point!
So I have joined the very brave souls club and ordered one. After the research I no longer feel like it's so much about being brave in terms of it working or being accurate but I do worry about the dependency on the company to make money and stay alive in order for my system to keep working.
