Jebao DP-4 dosing pump question

Hey guys, just a quick question. Does anyone have experience/thoughts that they would like to share about the Jebao DP-4 dosing pump? I'm lookin into getting one to dose Mag, Cal, Alk and vodka carbon dose. From my experience with Jebao is that it is a reliable product with wavemaker just not familiar with their dosing pumps. I'm wanting to automate what I can so that if I were to go away on vacation I don't need someone to do these thing for me and so that I can be away for me than 3 days without worrying if my parameters will drop too far.

Thanks in advance!
