15pcs Test Back Probe Pin,0.7mm on-Destructive Pin Test Probes Pin Insulation Piercing Needle Multimeter Test Probe for 4mm Banana Plug

I like the fact that the tips have a cover so you don't get stabbed

Work well very sharp contact edge for good readings

What you would expect for the price. Not the highest quality, but good enough go use regularly. The two peice plastic where the head connects to the body feels a little weak but they haven't popped off yet. Long as your not super rough. They should last for a while. The caps are not rubber like the more expensive ones so they don't rub on. Just slide on, so it's easy to loose the caps.

Perfect

I ordered the probe pins so that I could work on my son's car. The connector block was so small that I could not access contacts to check voltage during the problem diagnostic. The probe pins worked great for this activity. They were easy to slip between the pin and the connector so I could measure the voltage. The supplier delivered them on time and in good condition. I recommend them.

Auto electric repair, I like

Ohmic value varies slightly as you rock the needle. Not solid and steady. Better ones can be found easily.

High resistance 5 to 25 Ohms Not suitable for troubleshooting. Took a few apart body is made of pot metal with a stainless steel needle. Needle is not soldered or appear to be crimped very well. Your ohmic value will swing wildly as needle is rocked.

A must for any automotive technician. I prefer this style of pin over the style you use with alligator clips. Less chance of a poor reading. This style pin connects directly to your multimeter or scopes leads.

Costano poco, sono comodi da usare e sottili; finché si misurano tensioni funzionano bene. Hanno però una impedenza di contatto elevata e pure variabile, fino a 3 ohm, dovuta alla costruzione interna crimpata, che le rende non adatte a misure di resistenza inferiori a 100 ohm. Si possono aprire per fare un punto di saldatura all'interno si riduce questa a 200 mohm, costanti. Suggerirei di farlo anche al costruttore...

Poor connection and height resistance not ideal for diag

Carried out resistance check through the probe alone, resistance varried drastically from high to low, looks like a safety pin crimped into a sleeve, very poor, not advised for electrical tests.
