Tools and Hardware Reviews of CircuitWriterTM Precision Pen silver-based 4 grams

Customer Review: 3 words...Does Not Work
Summary: 1 Stars

You might as well use a piece of a plastic bag to connect points. Tried every way I could to get it to be conductive. drawing a line on a circuit board and letting it dry, drawing a line and baking it as directed to "cure it" I even tried to see if it was conductive little copper circle to little copper circle on a board with the copper on it.
It may work for itty-bitty breaks on a drefroster on your back window, but as for it being some way of conducting from point A to B forget it.
I cannot believe I wasted my money, could have bought 3 spools of 22 gauge wire for less @ Radio Shack for the price of basically nothing. Just a bag of "magic beans" when it comes to living up to description.
