GREAT - Perfect for converting the Thermomix TM5 from EU to USA.

. I have an EU powered Thermomix TM5 so the voltage is not compatible. The thermomix itself told me it would never work and I had to buy a new one again. However, after doing some research, I saw that people were making money from this product, so I gave it a try. I was concerned that while the wattage would be okay the heating elements might not be hot enough so I bought the 5000W. to be sure and it works great! I would highly recommend this product to anyone.

Pros
  • . Easy to use.
Cons
  • . Little things.

Used after 3 months for power converters

Bought 2 units to move to Europe, after 3 months of constant daily use, all household items, vacuum cleaner, Gaggia coffee grinder and coffee maker, all stereos, Marantz , Panasonic phones , drills , Puzzle etc etc. Works like a charm. I was a little worried about the negative and bad reviews, the lack of an unpleasant smell, burning smell and so on. The only thing that now and then when switching on is a popping noise when the transformer is switched on, but so far so good. Strange that I…

  • Very good price

Best Converter!: Power Converters

We bought this to use our kotatsu (Japanese heated floor table). Since we brought it with us when we lived abroad, we needed a converter that changes the voltage from 220 to 110. Most other converters we've bought and used in the past have either died too soon or blown fuses too easily. We were pleasantly surprised that the fuse hadn't blown after we connected the converter and then the Kotatsu and flicked the switch. The table was just warmed up and the family was just happy, I'm so happy with

THIS IS NOT A TRANSFORMER, IT IS AN AUTOTRANSFORMER = ZERO ISOLATION!

Note: This is only a non-insulating AUTOTRANSFORMER, it is not a real transformer at all pure power 110-120 volts without conduction of the high voltage line and internal safety GF, like a traditional transformer. This item cannot be used to safely convert US 220VAC to 110VAC, POINT. The item description does not warn of this autotransformer wiring. I couldn't believe how dangerous a 2kw direct drive product that could be sold in the US could be. It's not even worth my time to return it and…

Great product, reliable! The location of the outlets could be better.

Will be sent in a separate box-in-a-box...much heavier than I thought but very strong. I love that there are step up or step down options. I love it. With a lot of the equipment I am bringing as part of a move to the US where the countries where the equipment was purchased was 220v to 110v in the US this is very helpful. The only criticism is that the socket is located at the bottom of the device. So if this transformer is held in the table/tabletop for a while the output connectors should bend

Pros
  • Delivery was very quick
Cons
  • Questionable purchase for the elderly

Does what it's supposed to do, good value for money

I bought two 500 watt versions of this transformer to convert the voltage from 230 V from the mains to 110 to reduce / 120 V for use with US devices abroad. The Transformers appear to be well built, although one of them arrived slightly damaged (the case was bent on one side, probably because it had been dropped or hit something during shipping). As some other reviewers point out, they smell chemical upon unboxing. Based on the manufacturer's response to another review, it's likely some sort of

Pros
  • Satisfied so far
Cons
  • I really don't like anything about it, everything is fine
