Uli's Hotzone 4010, and it performed exceedingly well in multi-month testing, thus the JV, and now Uli is mass producing the units for the Mexican JV with GTEM's Mexican partner, VPN, owned by the Peraltas, who have made quite a bundle in the telecommunications field in Mexico and are one of the richest families in that country. Please, if you believe that the tests didn't work and the VPN engineers have been duped, better let them know right away. Show them your email from "alias one to alias two" . . . I'm sure they will believe it over their own testing! LOL
