Don't drop it on your foot, it's heavy AF. Check the dimensions—its not so much big in size as in size-to-weight. But that's to be expected with a 20 amp Variac. Also, the smaller models still weigh more than what you'd expect for the current that they carry. Not sure why that is, but probably has to do with voltage accuracy and thermal management. I felt like I should be able to get away with a much smaller, lighter device to manage voltage, but I'm sure they have valid reasons as materials are expensive, and most companies scrounge. This guy sits on my workbench right next to my DC bench supply and has come in handy for a lot of things. It's very accurate and sturdy, and the only issue I've had is that it's hard to read where the dial is from a distance. I used a label maker to print a black and white arrow for this, but it's still facing away from me if the voltage is set anywhere below 90-ish volts. The LED inside the power switch does seem to come in handy for me, and I may have to make an LED stack just to show voltage output. Maybe they should have a model that includes one; that would help. For the price, it's a steal. These things seem to appreciate with time, so it's probably not going to lose value any time soon.
