Kamoer X4 WiFi Doser Dosing Pump

Its ok... Thats all.. It took me about 8 hourse of fooling with this thing to finally figure out the app and calibration procedures.... The app and wifi features are the main reason most people buy this dosing unit but the instructions are horrible and are lacking in any detail. The best way to operate and calibrate after realizing the app controls for this never worked is to do it manually on the unit itself, but this defeats the whole purpose of buying it for the wifi controls.. Its a sleek unit, terrible youtube video instructions by the company that are hard to understand, and honestly for this price It should be top of the line. I could have saved a $100 dollars and just went with the bubble mangus or Aquamedic unit that lack the wifi control options.. I pray it stays accurate with its dosing cause its in charge of a heavy SPS population of corals... Heres hoping!
