This unit is simple to operate and does it's job well. I would recommend getting a separate voltage monitor as the graduations on the knob as well as the meter are not as accurate as they should be. Other than than works fine.

This is a really nice variac for the money, with a smooth dial and stable AC voltage. The only reason I don't give it 5 stars is the voltage dial markers are not accurate. On the scale ring, 50V is actually 56V, and 110V is 119V. The needle gauge on the front panel is closer to actual, and it's best to use a digital multimeter to dial in the voltage you really want. But this minor imperfection aside, it's a very nice unit at an excellent price point.

I bought it to run an industrial air purifier at 60 vac so I can stand the noise which is too much at 120 vac. I was skeptical at first because of the new electric smell and an imperfection in the paint job but the smell disappeared after a few days and now it's great.

Useful to regulate the power to my home coffee roaster to get a more even roast. I love this thing!
