Large Size Heavy Duty 3-48V Digital LCD Circuit Tester with 140 Inch Extended Spring Wire,Car Truck Low Voltage & Light Tester with Stainless Probe

pleased with product, use on farm equipment or anything 12 volt

A great test light. easy to read. Well package, came in really quick

It does what is supposed to do….just like apple pie and ice cream mmmmmm good.

Great tool, works great, easy to read. Quality Tool - The only thing I would change is the wire color, shoud be BLACK since it is the Black/Negative wire you will clamp to. Saves some confusion and follows color standards better. Actually, any color other than red would be better since it does have a black clamp cover to help.

This circuit tester is long overdue for automotive electrical trouble shooting, it works as advertised, reasonable price and NO BATTERIES required. Only used it twice, now its my first choice for 12 volt power supply issues

I install flatbeds and dump bodies on pick up trucks and I’m constantly wiring and this is the perfect tool for finding a positive wire. Works just as good as the $160 snap-on version.

Good piece of test/troubleshooting equipment to have. LED read out easy to read and much better than just a test lamp which only if voltage is there. Appears to be very heavy duty and the extended spring wire means it can be used to reach many more places. Great value, saves time and I recommend this test to any automotive guy. Highly recommended.

Had an issue they took care of it great customer service great tool

This tool is absolutely great but there is an issue with using this tool for what it is intended for, checking a circuit. Now I had a very simple low votage parasitic draw in my Harley Davidson. When I mean parasitic draw I mean under 0.007. I would normally pull out my multi meter to check the votage. My wife being the sweetheart she is purchased this tool to make my life easier. I used it, I found the draw was coming from my rectifier but this tiny draw ruined the LCD in the circuit tester. I went back into the Amazon app and purchased another one because it was as precise of my very expensive multi meter. I also bought 2.5 amp fuses and installed it where the springs are located. Problem solved. Now if JTS Jastind would simply install these fuses it would beat the other competitor who sells this tool for $150 (S??P-O?). I also see they sell extra LCD on Amazon. Make the product better please and give us the customer a better tool with an inexpensive fix. Could be 5 stars. Ill give 4 for being cheap.

Easy to use,feels very high quality on your hand,kind of a heavy tool for what it is but i guess is a good thing. You cant compare this unit to thise 8 dollar ones you buy at any Auto part stores,those are cheap quality,dont last that long and this unit top it off with the digital reader,CANT beat this for what u paying for.
