Review: Cheaper than its value - Very good and too sensitive. If the cable that is been traced is touching other cables , you have to separate them to be sure. This product is Better than some expensive products.
Review: Works good so far - Volume knob was a bit counterintuitive but works. Tested network terminations and toned cable. Works good so far. I like that it comes with an alligator clip wire set. Will be making a bnc wire set for analog camera lines
