Bests & Worsts Reviews from Amazon

So...when we get overseas and need to use/test it for the first time...nothing. Absolutely no output whatsoever. As a side note, I'm an Electrical Engineer and was definitely operating it properly. Fortunately was able to return for a full refund. BUT...obviously I could not easily test its voltage conversion function before I traveled, and to have it not work when we got overseas it was a major bummer. UPDATE: Now I'm being bombarded with requests to delete my bad review for a $40 Amazon Gift Card. So I'd imagine that a lot of people have accepted this offer and that in reality it should have a MUCH WORSE star rating.
