Hi gkbt, First of all, thanks a lot for sharing your experience in alkaline water system. It took me more than 1 hour to read and digest everything from page 1 to 9! I am looking at the Vesta, probably the 7 plates. You were saying something about it being touted in the US. I'm just wondering, are they exactly identical: Samsung Vesta (US) vs. Vesta (Singapore) or will there be a slight derivation? What about the panasonic 5 plates TK-7585, any thoughts on this one? It seems pretty cheap in Malaysia, RM 3,500 (~S$1367). Came across this comparison site, which is really useful, It even tells you which one is "medical device approved" and also factory/product certifications.
