Review on Norstar DAVR-1500 1500W Step Up/Down Voltage Transformer and Automatic 🔌 Voltage Regulator Stabilizer – Convert 110/120V to 220/240V or 220/240V to 110/120V by Kevin Silver

I finally have this device. It was defective: stop/start button with intermittent contact, intermittent screen, poor regulation calibration. I opened it up and put back the missing chemical capacitor! Replaced the on/off switch and recalibrated the instrument. I note that the interior is extremely poorly made with non-insulated sector wires along the body (in fact, the fragile back cover was deformed during transport due to the weight of the transformer). This product is far from meeting European and, of course, American standards. But after a solid update I leave this device still working.
