I received the new Kamoer X1 Pro head and just calibrated and tested it. Setup was trouble free.
I tested the same way I tested the Red Sea units: Dosing RODI into a beaker on a gram scale.
The Kamoer is accurate... tell it to dose 10ml and the scale is is reading 10.00, tell it dose 8ml and the scale reads 8.00. So, you cannot go wrong with either unit. The only further test is to see how well both units hold calibration going forward.
