My goldsource ST-1500 pro step up & down transformer

Okay, I owned this step down transformer since 2020 since my pifco princess hairdryer from the UK Was motorized on 240V. So I’ve been a USA science of UK electronics, so, probably my area is 100V-120V.

According To @hoover1060, @KirbyVacuumCollectorFixer, @Myhooverco8, @ArbokLover1618, @biotek6 & Every Vacuum Youtubers, They Bought In Their Step Down Transformers For 200-240 Volt Motorized Vacuums.
