  • It works if you're careful
Size: KM10
I had used it for about a year, no major issues. My only issue with the design is the length of the grounding cable, just a bit short for what I usually need it for, but I've been able to make it work with an extra wire. The only real problem I came across was when I had made the mistake of trying to apply power or ground to a wire when it had the other already active. User error, really. But it was when I kept doing it when I had to apply one of the two before making contact, like in a tight space. It would normally shut down and restart if you made a mistake, like normal. But I had done it quite a few times in a row and it had shut down completely. Few days later, it starting working again, but sometimes when you power it, it doesn't show or do anything on the screen but a blank background. Again, user error caused it. But other than that, having it as a mobile mechanic has saved me so much time, being able to see what is actually happening. I only have the KM10, but I honestly might upgrade to see what I can use the nicer model for. It was well worth the price. ... show more

  • Great tool
Size: KM50
So far excellent tool, I was able to test my a/c fan in a minute and found out the fan was the problem. Don't need to be a mechanic to buy it, I really recommend it

  • pretty good
Size: KM50
i dont like the fact that no attachments were provided to get inside fuse box pins for relay testing etc. - the tip on this is too thick for a lot of the work this is meant for, like backprobing connectors - you can kind of jerry-rig needle multimeter attachments on top of it but its not great

  • Great unit for the money
Size: KM10
This off brand power probe is fantastic! I Work in a shop with 4 other techs . Them having power probe branded and a snap on branded electrical testers and stand by them . But the cost of over $150 for a power probe brand and over $300 for the snap on branded testers was a bit much to choke down for a tool I use maybe 2-3 times every few weeks . So thought I’d give this one a shot and I’m not disappointed in my decision. Life is expensive enough don’t put your self in debt on a tool truck buy this and stay off that tool truck not about that $50 dollars a week for the rest of your life ! ... show more

  • PERFECT FOR THE DIY MECHANIC!
Size: KM50
I was a complete novice when it comes to electrical testing, but the clear instructions and easy to use device made it easy for me to diagnose what worked and what did not in my vintage vehicle. The built-in circuit breaker made it easy to accurately test grounds and it was easy to find working and non-working circuits. Saved me THOUSANDS in mechanic costs because I was able to fix my car myself. INDISPENSABLE TOOL!! ... show more

  • Broken right out of box, then started working next time
Size: KM10
Screen lights up but is always blank, either circuits bad or screen it, but it's doa right out of the box, literally the first time I used it, the same day it arrived. Should not have bought a cheap clone. Next day, I was going to use the non digital parts to chase down my issue, and it started working and I liked it. Since that one was flaky, I got another to try, seems to work, bumping 3 to 3 stars, will update next time I use it, but it's pretty infrequent, that I chase the kind of electrical issue that needs more than just a test light so it might be a while. They did refund the price with no complaints, so that's good. Liked customer service If it seems reliable I'll update the review later. ... show more
