  • 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

  • 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

  • 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 for Automotive
Size: KM10
My first review because I'm impressed. DC voltage range 0-65V. Works with 6v, 12v, 24v systems. In A/C mode, the simple waveform screen will show an acceptable 5Khz (or less) square wave, above that the corners will round, 10Khz max for sine wave; so its good for quick test of crank & cam sensors and injector pulses during crank only. Also get speaker sound of the A/C signal which can be very helpful. Should work with digital MAF, I don't have one to test. Surprisingly the manual is quite clear and informative. Manual states auto circuit breaker is 10A with 15 second recovery time. They recommend you trip the breaker to probe computer wires (can't apply 12V, but all other functions still work), but this is not reliable. Use on computer leads at your own risk. Don't bump that rocker switch and apply 12v to the computer! Also impressed by the diode test which measures the forward voltage using a 3v source. ... show more

  • Just as good as the power probe, fraction of the price.
Size: KM10
I know, I know. This is a cheap knock-off of the power probe. I don't even remember why I bought it. I think the power probe wasn't going to ship for a few weeks, and I needed to troubleshoot something ASAP. So, I bought this thing and it came in the mail in a day or two. So, I started using it, and it has paid for itself more than two or three times. It allows me to troubleshoot, read voltage, amps, resistance. It is great. Plus a handy little light for night operations. Plus, very very long lines/cables mean I can even work on the boat without stressing or pulling cables. I really mean it. This thing is great!!! ... show more
