  • Easy to Use, Quality Product.
Packaging exceeds my expectations, definitely better than its competitors. I’m impressed with the product design. It is an excellent item, with lots of features, and it can perform many different tests. Great quality product at an affordable price. I like the power feature as it allows components and circuits to be tested which helps when trying to trace and troubleshoot electrical circuits. ... show more

  • Very solid tool for troubleshooting and testing.
I picked this up to help with some wiring Gremlins chasing down problems with window motors And lock switches. This definitely a beats the jumpers that I made out of speaker wire plugging directly into the battery. It has become most useful tool at the moment and the build quality is not questionable at all. I feel confident this power probe will last me a very long time. ... show more

  • Great value
This product has saved me time and money! While other mechanics spent hundreds of dollars for a product very similar to this, I saved by purchasing this product and it does exactly the same as their name brand probes and has held up very well. The flash light in the end of the probe is a very bright and nice feature to help in those hard to reach and dark spots. Highly recommend if your trying to save some money. ... show more

  • Well made but
The media could not be loaded. No external circuit breaker or the ability to cut off the sound.

  • It's awesome
I don't know how I've ever gone this far without ever owning one of these. Do yourself a favor and buy it. It saves so much time and effort into diagnosing things. The fuel injector tester and cleaner plus the relay tester just makes this tool absolutely mind blowing. I love it.

  • Worthless. Quit working after 7 uses
I really liked the product and it's abilities. I am a mechanic and this is not a tool used on a daily basis. I used it 7 times in a month and a half. It completely quit working and at that point was past the 30 day return window. There is no way to contact the seller. Amazon is doing a return but charges a restocking fee of $10.00! Beware of a seller that only gives 30 days and no contact information! You will get screwed with unreliable products and no help! ... show more
