The product seems amazing, but they are somehow cheating in the video. The signs (in Spanish) have grammar mistakes, but they are automatically translated to correct English sentences. I have a few examples: - The third sign says "Lo traduce el texto", but that sentence doesn't make sense. It should be "Traduce el texto" or even "Se traduce el texto". - 'Ropas opcional' sounds strange to me, although it may be accepted in some countries.. It should be something like 'Ropas opcionales'. I tried both examples in Google, Bing and Babel Fish and the results were OK, so I don't think that Word Lens translator is very accurate. "Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" ... I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question."
