This was a nice replacement for my 30 years old unit, works great. Super fast shipping and no damage.

Have used it a few times seems to work well. I use it to control my band saw speed. I have not had any issues so far. Quality seems good. Shipping was fast.
Solid auto transformer
Bought this to simulate a brownout for testing electrical equipment and could not be happier with it. Works awesome

Works Great!
I have had 3 of the $20 variable transformers and wish I would know about this before I bought them ... everyone of them has broken. This thing is heavy and built pretty good. I just wish it would have had some kind of swing handle because you have to use both hands to pick it up. Used it with my router and buffer and angle grinder and works extremely well with all.

searched for a long time to find one. It is heavier than what I wanted and only has one plug but it works as expected.
Look for the oulet configuration to choose right model!
I ordered the autoxmer following the description for 0-230VAC output and I received a 0-130VAC. I returned it flawlessly the next day and reorder based on the images, not the description, and received what I was expecting 0-230 VAC.Please notice that in the images, the 0-130VAC has TWO regular outlets and a digital meter, while the 2-230VAC (actually about 0-250VAC) has ONE universal outlet and an analog voltmeter (which I replaced easily with a voltage-current digital meter:, although you need to desolder the output line to place the current transformer, no big deal).If you need 0-230VAC and less than 8 Amps for your output YES, I recommend this item. It is worth every penny! If you need more power, be prepared to pay much more money if you find one that is deliverable.

It works well!
I like the appearance and the luminous display although the display shows a higher output voltage than an external voltmeter reading, but it's close enough.

A little scary
Shoots sparks at times, no house fire yet

Good enough
For my limited use, this is a good variac. I prefer to by genuine American brands, but$530 is way too much , all I do is lower voltage to Guitar amp to adjust tone.I was surprised at how heavy it is.
