thats a good deal, but Milwaukee is not one I am familiar with, I will only trust oak ton, Hanna, and blulab, with blulab and hanna being the ones i know even when they break I have a chance of getting a new one or a replacement. but that is a good deal, add a tds in their and then about 50-60 bucks in solution and;... well now I see it is just about 20, bucks cheaper but still not too bad. I really like the all in one monitors, one you don't need as much solution waste and 2 it is much easier to get 3 readings at one time then 3 separate readings, but I like the 20 dollar option too.
