After hearing so many good reviews, I finally bought the Hexprog II from
ecutools.eu They had the full kit in stock with BDM cables and activation ready. I mainly needed it for BMW and Mercedes ECUs, but their site also offers extra modules for EEPROM work and immo data. Shipping to Europe took only a few days, and support sent manuals and updates right away. If you’re looking for professional-grade ECU or EEPROM equipment, check their official catalog here
