Been watching this thread for a few weeks now, but now I can join in! Received my Reefbot this week a few days before DHL's expected delivery because customs was working on Sunday evening at LAX (not going to complain, but what?!). They were serious though, when they emphasized delivery by 8PM--it came it at 7:53 PM.
I work in biology and genetics labs with automation solutions, so I found the setup and usage very easy. I decided to follow the app's instructions on not calibrating the delivery solutions (even though the flier enclosed provided directions, the app's emphasis on not doing it made me experiment). So far KH and PO4 (both Red Sea Pro) are spot on to what I expect compared to manual measurements. I am also using the Red Sea Calcium, and that one has been really off, mostly due to no change in the color (pink registers, but no blue or a really late change to blue). Filed a support request.
As a plus, the other half loves the Reefbot because of the potential to not need to perform daily KH, Ca, and Mg tests :):D.
