PARTS EXPRESS 110/220 VAC 500W Foreign Travel AC Voltage Converter

Before I begin this review, please note I did not purchase this product from Amazon. However it was such a terrible product I felt compelled to warn others.Put simply, this product is the epitome of low quality questionable Chinese manufacturing. The first thing you will notice is the overwhelming chemical smell as soon as you open package, smells downright poisonous. Gasoline has a less intense smell than this product. Not almost a month later it still smells as strongly. This alone is a disqualifying factor as the odor will take over your room. Clearly something wrong here. I went back to the store I bought it from and they all smelled this way including different models by same manufacturer.Add to the smell an audible humming sound when it's powered on, which can also be problematic. In my case using it for European music gear running in the states, as such humming sound not good for recording conditions. Also loud enough to be annoying.On top of it, customer service is non existent and it appears this manufacturer offers no warranty whatsoever, which makes sense when you're peddling complete garbage.Given the issues with this unit, I question wether it's even safe. Quite frankly this product should be removed from the Amazon marketplace. Avoid this product and manufacturer at all costs.
