I did not use this travel voltage converter for its intended use, so I can't comment on its suitability compared to other products on the market. I needed a step down power transformer to use in an "industrial" application and it worked perfect for my application at a very low purchase price. I chose this unit for its attached power cord which lets you locate the transformer away from the wall outlet, a critical feature for me. I purchased three and they are all in use. The build quality is good and I've had no problems.One Way Voltage Converter 220/240V to 110/120V AC - 200 Watt
