Made in India or China!! The exporter is not very forthcoming.They are purchased by retailers through an exporters hub to hide their real identity. Even they don't know who the hell made them.
Replacement Parts can be purchased here, however they seem to be made by a bunch of different manufacturers, none being Ultrex, so I was unable to find a manual.
You should contact them to see if they can get you one. The model number (08333) is useless to this site, but there are good pictures for all the parts that are supposed to fit a Ultrex blender.This is the only association with Ultrex that I could find. Good luck.
