The Customs form attached to the box will say US made.
P.S. I'm currently using Duracell Professional batteries, made by a division of a Canadian company in Toronto.
I'm considering buying one of your "Harmonizers". What kind of batteries does the unit use? Are they rechargeables or replaceables? If the former what method, if any, is included for recharging?
