Review on Sperry Instruments ET64220 Wire Tracker Wire Tracer: A Must-Have for Audio / Video Installers, Coax, CAT 5, Speaker & Phone, with Adapter Plugs (RJ-45, RJ-11, Coax & More) - Yellow by Zachary Caldwell

I rarely use this tool. When not in use, it sits neatly in the tool box. I used it today for the first time in years and the tip broke with almost no pressure. The attached photos show how fragile the tip of this tool is. It was barely held in place by fragile glue and very thin wires. Even if you don't use this tool often, you can expect the glue to become brittle and no longer stick, then you can expect the tip to come loose. I wouldn't say that this tool costs close to $40.
