## Customer Reviews

### ⭐⭐⭐⭐⭐ Works Great
*by D***. on July 8, 2024*

Moved from the U.S. to Europe and decided to bring some great kitchen electronics we had with us. This allows us to use things like rice cookers, mixers, etc. it works great and is able to handle the voltage difference here. It’s large and heavy, but so are some the appliance we plug into it. Makes no noise while operating.

### ⭐⭐⭐⭐⭐ Nice product, sturdy and good quality
*by A***R on January 8, 2016*

I (stupidly) moved a coffee machine, slow cooker and a few other electronics from South Africa to the USA recently. Yes, a stupid decision, but I purchased this converter to use those appliances and so far so good. We have used the converter a few times a day for 2 weeks with no issues so far. Yes, its pretty heavy but nothing excessive. It has a nice handle which makes it convenient to carry. I could not find any converter which would accommodate the massive South African 3 prong plug but I have tons of international adapters around the house and it works just fine with one of those. I have not experienced any loud noise - you can hear a very quiet humming noise if you are in complete silence but that is about it. In all, the converter is sturdy and seems to be of good quality.

### ⭐⭐⭐⭐⭐ Singer Featherweight 222K
*by C***. on August 29, 2017*

I bought the 500w model to use with my Singer Featherweight 222K sewing machine. Call me a purist, but I wanted to use the machine as it was originally made and not converted to US power. The instructions say to figure 3x the watts needed, so I got the 500w model. Received item unharmed, read instructions, and plugged it up. Works well. It has a low humming noise, but not noticeable while on the floor in use. I only plug it in when using it, otherwise keep it unplugged. This brand was the only one I found with a good warranty. It may be a few dollars more, but considering the item I'm using it with, it's definitely worth it. Highly recommend to my Facebook friends in the Feathweight group page, as well as anyone looking to use with a precious Featherweight.
