CMTOOL Automotive Circuit Probe Tester 6V 12V 24V Car Power Circuit Probe Kit 6-30V Led Test Light Tester Short Finder Master Kit AC DC Voltage Resistance Diode Electrical System Test Diagnostic Tool

Great for checking power and grounds on cars and trucks. I bought this for working on fiverglass boat. It check power and grounds. I keep this on my boat

Works as well as the high dollar power probe I have work, what else can you ask for?! The 2nd ground could be slightly longer but works fine as is.

Very convenient and handy

put the right manual in the box,, cant say it caused a problem with the operation and understanding of the tool, but come on

Easy to use and quick service delivery. Must have for any mechanic

On the add are quite a few similar units but have different specs. Not only color but longer leads as well. In hindsight I would have liked. A longer lead to get to battery. Not sending it back as freight cost are as much as unit is worth.

Easy to use

I really wanted to like this because of the price. That low price comes at the cost of no voltmeter. Power and ground can be sent and it will pick them up but that is all. It is very inexpensive though. I wish I would have spent a little more and got one with a voltmeter.

Test, dont guess. Had a potentially bad fuel pump but wanted to confirm. Bought this and was able to confirm the pump was bad. But also figured out the bad pump had taken out a fuse. Glad I had this or I would have installed the new pump and wondered why it still didnt work. A great addition to any automotive toolbox.
