Review on 🌬️ KT-401 Mini Air Ion Tester: Accurate LCD Display of High +/- Air Ion Concentrations by Jeffrey Johnston

Like a good metal detector looking for a source! The numbers fly up and down! until you do! Big minus 1! Shows Max Out! The square wall wart was weak! And a flat black magic wand with a wire brush looks great! eye opener? opinion changer? Thanks again Revan! Important ? These negative ions are called vitamins in the air! So small! Easy to keep with you!
