  • A must have for mechanics
Style: P200
I bought this tool over six months ago and use it almost every day for my work. It has proved to always be accurate and therefore be very reliable. After realizing the power probe hook went off the market I did my research and ended up with this one thinking it would be a low risk investment due to the price comparison of powerprobe or Snapon. It has survived being dropped and handled normal wear in a shop environment. I use every function on it besides the diode tester( due to not having many opportunities in an automotive setting) and especially appreciate the one channel lab scope( something not available in name brand powerprobes). The only drawback is it only operates and reads in DC voltage, something to keep in mind when using the multimeter and oscilloscope setting. Overall amazing tool and passed my expectation on durability. ... show more

  • Inclusive kit
Style: P200
This is a useful and handy all inclusive kit, that is great to have on hand. I always like to stay prepared for any situation so this was perfect for me to keep in my car. It is pretty light weight and comes in a hard case for travel and storage. You get all the cables and connectors needed, and they work just as they are supposed to and user friendly. Not only does it come with good instructions, but it also has a CD which i found much more helpful! Good value for all you are getting. ... show more

  • Work the money
Style: P200
Great tool. Worth the money. It works great and i was able to easily test some tail lights and save money on replacing them when it was a bad wire. Cables are long enough to reach the length of tje car easily.

  • Big Gadget
Style: P200
This has all the bells and whistles, but not much other accessories. I had asked if they had an extension for working on trailer wiring, the seller wrote back and said one is not needed because of the 20' cord...(apparently short trailers in china). One thing I need for farm repairs is tracing trailer and damaged equipment wiring. I had to buy a 30' wire extension reel from HF., but that's not a great solution. There is a voltmeter (only to tenth of a volt), a ohmmeter/beeper, a relay test jig, crude o-scope, a wire identifier (indicates a + or a gnd source), an adjustable power source up to 5V @ 100ma for testing, and adjustable current limit feature to supply the tip with either a positive 12V or grounded tip (this is a relay switching circuit that you can hear when in pulse mode). This tip activation mode is controlled in the menu and may be safer than just a probe with a rocker switch... I don't know how robust this circuit is, just using it to test those pesky LED trailer lights so far, though it should test a brake coil (3-4A ea). This puts everything in one package but recommend at least have a good DMM, because the black lead is always grounded. It is hard to remember NOT to use it like a multimeter, don't measure across something unless it is disconnected. The assembled "smart hook" is huge with the probe attached, fortunately, you can remove the probe tip and use the jumper wire to the probe for using just the probe. I have not used its other features much, trailer wiring,AC relays and switches. I am not sure why this product would need an update, unless they suspected there were bugs, it is not a internet device. NOTE: while the hookup clamps are pretty large, one side of the jaw has no connection... There is no mention of how to use the current feature in the DMM section. You need to push the ok button ( push ok and arrow down at the same time to latch it on) and the green light comes on and supplies ground thru the meter tip to measure current. This means you need the power already supplied to the part. Hitting the ok button to deactivates the current mode,but one time it stayed on and I had to disconnect power to reset it(bug). Another way would be to use the "activation" to supply power and that reads current, B+ voltage and tip voltage (load voltage) up to the set limit. There is a link for the manual on the amazon page. ... show more
