Puncture Probe Wire Piercing Test Clip 2PCS P5010 Automotive Test Cable Kit Auto Car Repairing Multimeter Testing Tool

Cost effective

Makes probe testing easy and quick with a good connection. It also fits up perfectly with my snap on lab scope. They are not the strongest plastic but they get the job done.

Working great for me

Just push down on the spring loaded part and pull up to puncture the insulation. Although I am loathe to damage any insulation, just two wraps with electrical tape and it is as good as new.It;s nice that my multimeter probes fit these probe holes perfectly.The black one is great for checking resistance to ground (Bad grounds) and the red one is good for any positive voltage signal.

Not cheap looking.

Quality seems cheap and they are sticky.The piercing probe sticks. Maybe a little lube may help.

Looked for something like this for years. First set I was unable to figure it out as there are no directions. To me this was a new tool. It really does make a tiny pin prick in a wire and with an assistant you can label which wire controls the turn signals and the brake light and the flashers or any other wire you need to connect. If you are concverned about a pin prick in a wire get a bottle of plastic coat that makes a seal on the wire you just pin-pricked to identity its function or you can put a small piece of tape or use that spot to attach a T-Connector to. (Most wiring people will know what that is.).

Great product, use them at work often, great for the home mechanic. Test your wires without cutting thru them snd having to re tape them and leave it vulnerable for shorts later on. A true time saver around the shop.

Muy practico y se buena calidad

They work just fine.

Easy to use

Buen producto muy necesario para no estar pelando los cables automotrices durante las pruebas de continuidad y voltaje.

Serve there purpose worked well for my project. Glad to have them.
