Insulation Wire Piercing Probes - Automotive Diagnostic Test Accessories Repair Tools Needle/Back Probe kit(Set of 4)

Not bad. They work well. Only one minor issue. They are much smaller than the image appears. They do not need to be larger, that's not a problem at all. I was only seeking an automotive volt tester that pierced small wire insulation without missing the wire and poking my finger. In this case, size does not matter.

The probes were just as advertised, and will be a good addition to my tool box. The only problem I have with this order, is the attack spider that came rushing out of the box when I opened it. I did not order this spider, and it was not on the packing list. Should I return it in the box? Possibly someone else ordered it, and it was put in the wrong box.

They are good probes for the money, but there is no way to lock them once you have pierced a wire. You have to push the probe into the white part rather than screw it in. Not very secure.

Monitored pulse width of coil pack control circuit. Needle engaged fully, no issues.

These work, but are flimsy and awkward to use. You need to hold them in place, since they do not lock in place, and the circuit tap is way too large for any probe I have. That includes cheap craftsman meters and high quality MAC meter.

Look be exactly what I needed. I haven’t used all of them but played around with one and it’s of good quality and was described accurately.

Picture is deceiving. Product is very small and the 2 parts are not permanently affixed together, rather they easily come apart. My packaging/case came broken and products felt flimsy and VERY cheap. Not what I was looking for or I expected.

I love the product. It makes testing wires in hard to reach places so much easier no more poking my fingers.
