allsun Automotive Electrical Circuit Tester Probe 2-24V DC Pen Vehicle Power Diagnostic Tool Auto Wire Test Light Device System Analyzer

It works but the battery is very bad

Enabled me to diagnose car power window. Window would not go up. Was able to use short jumper wire/ground to window motor and use this tool as power probe to actuate motor to ra it se window. Awaiting new master switch to complete repair. Best $20 spent in a tool!

For the money, perfect. One poke and I knew what I needed to replace. Device was getting voltage which the probe makes a sound and light. I sent voltage to force it, and nothing. 2 minutes to hook up and test to get my answer, great product.

a must have product for any car electrical repair, makes it so easy

Mine already dont work... only used it a handful of times. However, the company reached out to me to resolve my problem and has since offered to replace it. So far I am very pleased with my experience... ...sent a new device in place of the defective unit. 5 star customer service

I couldn’t tell you if this is a good product because it didn’t come with the probe.

Works well for the price. The cord is long and usefull when working on large RVs

My first one shorted out when I hooked it up to the battery. Called for another under warranty but still ended up paying for both.

Does what it supposed to excellent product fast delivery!!!

great for troubleshooting trailer wiring, testing lights, etc. Sort of wished I bought the one with a digital volt read out, but I can get by fine with this. Long cord and sharp probe.
