Lost the charging cable for my old brand-name Waterpik recently and they want $50 for just the cable. Saw this in-store at Woolies Marrickville for $30 off and decided $70 isn't THAT much more than $50. Seems pretty decent a few days in. Construction may be slightly flimsier than my old Waterpik but the jet is nice and strong. Noticed Amazon AU has the same price running, but it looks like it typically goes for around $100 at chemists and other outlets.
