Shouldn't need 50/60Hz unless travelling abroad with it.
Or is it easier/cheaper to find a 50/60Hz model?
I really doubt any juicer has electronics that running 50Hz would change things too much. Although if you know for sure a 60Hz grinder loses too much power, then your friend may be right...
Just curious about how to juice in Jamaica...Carambolo, Duppy Soursop, Ja Mango, Mammy, Naseberry, Otaheite, Star Apple
