GHL ProfiLux Doser 2 w/Wi-Fi Controller

Ok I bought one, tried the Jebao DP-4 doser and it just didn't prove trustworthy after a couple weeks of testing. Cant tell you how many times
I calibrated it and every day it dosed up to 200% of what I had it set to dose. No way I was trusting it with my SPS tank. The GHL wasn't cheap but they were running a 25% off sale and GHL had some great reviews so I bought it.

This unit feels solid and the android app makes it real easy to calibrate and program. Looks like it does a lot more than just dose but I'll explore more once I'm satisfied in its dosing accuracy. My only complaint so far is that it's not iOs compatible so I had to buy a $50 Android tablet to program it (not so bad after the sale price).
 
I looked into these a while back and if say they are the best dosers on the market now. With the stepper motor, the controllability and customer service of GHL you can't go wrong.
 
I have but I need this for 2 tanks and primary need is to keep ALK stable, I'm only dosing a total of 40ml daily. A CA just seemed to be too much for so little. Maybe on the next (bigger) tank.
