Bests & Worsts Reviews from Amazon

I bought this Foval Power Step Down unit to use in the UK. It worked just fine for 6 weeks. I found that the "white noise" of the unit's cooling fan about which others complained is hardly noticeable, and the fan keeps the unit at a comfortable temperature. However, in week 7, one of the two outlets on the top of unit stopped working. Nothing that I tried could revive it. I contacted Amazon to report the issue and was given the manufacturer's contact phone number to file a warranty claim. Amazon could not give me an on-line customer service site for the manufacturer. I found that the phone number is registered in the old soviet union, and can not be reached from a US phone except as an international toll call. Amazon, to its credit, ultimately stood behind the product and refunded my purchase price. But I have to rate the product as unacceptable for two reasons: a) an important component (the outlet) failed after only 7 weeks and b) the manufacturer effectively does not stand behind the product - there is no way to reach them - so the warranty is useless. I hope that Amazon discontinues carrying this substandard product, and that Amazon better checks out its vendors before selling their products. Too bad too: the product as described fits needs of an international traveler, but in practice isn't durable or supported.
