Arrived in perfect shape, with a pack of extra fuses. Haven't needed one yet. This sort of variac is only useful in some very slim scenarios, for relatively few things - particularly, controlling the speed of certain types of motors (shaded pole, and maybe universal), or the brightness of certain types of lights (incandescent, or some LEDs that are line-driven with no other intelligent power supply inside). Given its limited uses (and ways it can cause problems in inappropriate use cases), I expect people to frequently buy this thing for the wrong application. In my case, I bought this along with an inflatable projector screen - so I could control the speed of the blower and make it silent (and draw less power, as I'd be powering it on battery), while still keeping the screen inflated. Indeed, around 50% speed, the screen stays inflated and silent. Works great for fans and blowers!

Good size and capacity for guitar amplifier safe start-up procedures.

the VU meter matches the dial labeling but nether of those match actual output voltage. the dial is labeled in increments of 13 volts and for every increment +1v or +2v is added to the actual voltage so at 13v dial setting I get 15v, at 26v dial setting I get 30v, etc. at 130v dial setting I get 148v output. output spikes -1.3v at max output (148v) and -0.6v at near min setting (2v) periodically (~2hz, smooth spike). aside from this spike voltage is +/- 0.1v for about 70% of the time, the other 30% being that spike happening. attached is a multi meter test for the dial sweep. dial was turned from min to max to min at a more or less constant rate a few times. voltage spike happens with my unit at around 25v and its significant. you can see it in the picture. the rest of the transition from min voltage to max is smooth. scale of the graph is 0v-160v mean is 80v. also attached is oscilloscope reading of the output at 2v. my scope is only rated for 10v max and im not going to push it with this unit. shows 60hz +/- 0.1hz with a periodic spike in hz every so often which makes it dip to sub 20hz. spike is super short (a few microsecond or less is my guess, didn't bother to try and catch it on the scope to measure it explicitly.) and happens less than once per second so no big deal. you can see that spike measured in the statistics frame on the oscilloscope image under the Min column, average column is still close to 60z so its not a significant spike. if you care about a spike that short you probably care about the waveform too - scope shows a pretty clean saw waveform, not sine wave. this aint guna be lab gear. all in all, for the price, its fine. its not supposed to be lab equipment and as long as you mind the actual output voltage it should work well. im pretty happy with it. UPDATE: been running 24/7 for 11 months, no issues at all.

Look, this is a low capacity model. I use it to regulate a small cooling fan. For that, it’s OK. I wouldn’t dream of using it to fire up some aged tube amps as it doesn’t have the current capacity. So for lights, fans, and other low power devices this is a handy thing to have. Build quality seems passable, but I haven’t had it very long.

Good product but power switch broken after one year. I have to purchase the same power switch and put it back on, on all three voltage regulators I brought. Not too much of a problem though, on my side. * I also recently attached a power drain to this regular, to make my drainage snake to be motorized with controlled speed, this has saved me a few hundred dollars for buying a motorized drainage snake. Great product.
