I've been running one of these for a couple of months and love it!
I just got a second one. As much as I like it, I don't really need two...brand new, still in the bag. $25 (retails at $40)
If you already have an RO/DI or just DI system for generating your water, you probably don't check the output quality of the system often enough. I know I didn't. I trusted the color changing resin to tell me when to change. I have a hand TDS meter but I just rarely used it. To complicate things even more, I keep buffer in my DI reservoir, so checking with hand meter always required unhooking the output line and running some water into a glass...
Now I check it every time I run the system. This meter takes about 5 minutes to install--just turn off incoming water, cut the 1/4"supply line and the final purified water line, insert the speedfit Tees with the meters, connect the wires to the small display unit. That's it. The velcro tape is the most technical part of the job.
Just press a button to turn the display on (has auto-off to save batteries) and slide the switch between incoming and outgoing. I confirmed that my incoming water runs between 250 and 320 ppm (which I kind of knew, but didn't check once the filter system was up and running) and my output with new DI resin is rock solid 0. What I learned new is that the quality of my output water started to degrade before the two DI resin cannisters were completely brown. By the time the second was actually fully changed, the water was coming out with higher TDS readings than the incoming city water!
This is a great $40 addition to quickly and easily verify that the water you are using for top-off is actually as pure as you think it is.
