Yeh I know what you mean, I definately need to get a TDS meter anyway, but the machine actually did give a choice between just RO or RO/DI. I must say that although my marine experience is not very great, I still believe it to be a reliable source of good water cheap. Maybe its my bias, I did work at a whole foods for a few years, but they have all the info right there. I'll test it though, it'll be interesting to see what it comes out too.
