milwaukee or pinpoint ph monitor ???

I've only used pinpoint and have always been happy with it. Easy to calibrate and I believe to be quite accurate. :)
 
stay away from reef fanatic. They can't even give you correct instructions on how to calibrate the unit.
 
From what I hear, the pinpoint (which I have and am happy with) goes to the hundredths, while the milwaukee only goes to tenths.

My only complaint with the pinpoint (and I've never had any other, so this could be true of them all) is that it can be affected by electrical interference, in my case specifically, from my VHO lights. When I installed the VHOs, I started seeing a lot of rapid fluctuation in the reading, +/-.05 from the actual reading. As long as I keep it away from other electrical equipment, it's fine.
