Hello gkbt, Am thinking of a system from KT. Appreciate your views on: 1. Smart I 7 plates vs 5 plates? Pros n cons? 2. For us to bottle this water for school and work, what is the recommended bottle types? Stainless steel or plastic? Switched to SS 2 yrs ago due to possible plastic leaking into water, so with high ionized alkaline water, what is the impact? Will the antioxidant deteriorate to zero for 8-9 hrs that we were consuming this water? 3. Recommended alkaline level for primary students? Thanks!
