    This Thing Has Made Bench Work So Much Easier
    Been using this variac for a few months now on various projects – testing old power supplies, bringing up vintage gear slowly, and just having a adjustable AC source on hand whenever I need one. The LCD screen is a nice touch, lets you see the voltage at a glance without having to keep a separate multimeter hooked up all the time. The knob turns smooth and the whole thing feels well built. Handles everything I throw at it without breaking a sweat. If you do any kind of electrical work or repair, you'll wonder how you got by without one. Solid piece of kit.
