Geek

I don't know which of my online activities prompted Google to put an advertisement for one of these in my in-box on Christmas Day. Did it see the word 'geek' in the profile but not find any proper electrical toys on my Christmas present list?

Reference 1: http://www.siglent.com/ENs/. A company which does not admit to being Chinese, but which does have a strong whiff of China about its website. No idea what sort of people they are targeting with their products. Home electrical nuts? The security boys?
