Review on 3000 Watt Heavy Duty Voltage Converter Transformer - Step Up/Down Power Converter with Circuit Breaker Protection – AC 110V/120V/220V/240V – DC 5V USB Port - CE Certified - 3-Year Warranty by Chris Cervantes

Bought 2 units to move to Europe, after 3 months of constant daily use, all household items, vacuum cleaner, Gaggia coffee grinder and coffee maker, all stereos, Marantz , Panasonic phones , drills , Puzzle etc etc. Works like a charm. I was a little worried about the negative and bad reviews, the lack of an unpleasant smell, burning smell and so on. The only thing that now and then when switching on is a popping noise when the transformer is switched on, but so far so good. Strange that I bought 2 units, they just disappeared from Revain Europe. There is no way to comment or edit. I wonder what happens after the warranty if there is a problem.
