Query: Toylike junk

The problem with this item is poor design, and really cheap, toylike, quality. It's difficult to use, and I wouldn't trust the findings. This, to me, was a complete waste of money, and I'm puzzled as to how something so utterly junky, can get a foothold in this type of market. Hobbled together with ordinary alligator clips, wire, and common parts that are available almost anywhere, the question is what is it? My guess is that there's some sort of patent in the circuitry, and this explains why the price is so outrageous. Checking this product with other outlets, reveals what appears to be price fixing, because anybody selling it, charges the same price! My advice? Save your money, there are better ways to test your precious metals.
