Works like a charm
Bought it for my appliance from China, Worked like a charm. Very well designed and made, plug feels solid, no odd smell or noise. Highly recommended.

Works as advertised.
Product arrived quick. I've used the step up transformer for about 3 hours and it definitely works as advertised. Good simple instructions come with the unit. I don't have a way to test it for how many watts it puts out at this time. Would definitely recommend to this point.

Works great
Needed a step-up/down converter for a ps5 I bought in the UK (back in US now) this one was highly rated and it works like a charm. Great value, definitely be sure to give yourself wiggle room with wattage, went with 1000w but will never even come close to half that, I heard it helps with longevity though.

I have used many transformers- THis is by far the best I've used. 3000W
Most other step up step down transformers have heat issues and use poor quality electronics. This has almost no heat during operation and is the best build quality that I have run into. Way better than Rockstone or any off brands.
