Good quality
Overall item looks good, well made, but after abitof research, not used due to electrical issue on my car is common fault. So I decided to replace the tailgate wiring harness instead.

Not fit for purpose
This doesn't have the power to find a break in a cable longer than about 300mm from the sender unit .sent it back

Does not work….avoid!
Why did you choose this product over others?: I’ve a broken wire somewhere in the wiring loom between my car’s engine control unit and one of the injectors. I bought this to try and find the break but to be honest, it is nothing more than a noise maker. No matter how many times I ran the “wand” up and down the loom, even switching positions from top of the loom to the bottom, all I got was a constant drone that didn’t pinpoint the break. So I ended up buying new wire and running it from the ECU to the injector bypassing the broken wire which fixed the issue. This gadget is utterly useless for automotive purposes and has been returned.

As a master automotive technician with over 23 years of hands-on experience majority of my day to day involves in diagnostic work. I'm always on the lookout for tools that make the job more efficient and accurate. The V210 has quickly earned a spot among my daily go to diagnostic tools, especially when it comes to chasing down wiring issues like open or short circuits. Recently, I had a vehicle with an open fuse issue caused by an alternator wire that had broken at the connector and was shorting to ground. Using the V210, I was able to quickly pinpoint the issue without any guesswork. The process was smooth and painless, this tool made a potentially time consuming job quick and straightforward. What sets the V210 apart is its simplicity and effectiveness. It’s compact, easy to use, and extremely helpful for electrical diagnostics. If you do any kind of wiring or circuit work, this is one of those tools that will absolutely save you time and headaches. With all that being said, I do have two suggestions/recommendations that I hope the manufacturer considers in a future update: Continuity Testing with Audible Tone, Currently, the tool uses an LED indicator for continuity checks. Adding an audible tone would allow users to hear confirmation without needing to keep their eyes on the device, especially helpful in cramp areas like under dash or when working alone. Receiver LED Indicator: The receiver unit relies solely on an audible beep, which can be difficult to hear in a noisy shop environment. Adding an LED visual indicator would make the tool more accessible, especially for those who may be hard of hearing or working in loud areas. Overall the V210 is a highly capable and user-friendly tool that’s already proven its worth in my daily workflow. With a couple of small improvements, it could be nearly perfect. I highly recommend it to any tech who regularly works with vehicle electrical systems and it's very affordable!

Very useful tool. You can find breaks and test for continuity in wiring easily. The V210 is an easy to use system and it is simple. You get the hang of it almost instantly after using it your first time. To check for continuity in a while all you do is connect the two prongs on each end of the same wire you are testing, and set the transmitter to CONT. if the light turns green, you have continuity. To find a break in your wiring, you simply set the transmitter to TONE and put one prong on one end of the wire you are testing with any power and loads removed, and you use the receiver to follow the wiring harness down until the tone/jingle it is setting off stops playing and cuts off or goes very quick. That will tell you exactly where the break is. I will be using this tool as much as I can. I have already used it on a 2023 Toyota RAV4 that came in because it had a break in one of the wires for the front radar from a prior collision. Traced the harness back and found the break in no time. 5 stars to this tool.

This is an inexpensive and awesome tool to find electrical shorts or open circuits in automotive circuitry. The key to making this electrical device work correctly is to READ THE INSTRUCTIONS a few times as to familiarize how this tool works efficiently / properly. Remember to always shut off the transmitter and the sensing wand. Does not have auto shut off. Will drain the 9-volt batteries if you are not paying attention. Another point that should be noted and corrected by the manufacturer, the battery compartment was designed too small to fit the average 9-volt battery. Had to use Dremel to grind away the 4 light blue handle tabs protruding into the battery compartment. Needed to grind them back about 0.050 and also grind another 0.025 from the very bottom end of battery compartment because the 9-volt black plastic connecter cap is too thick when connected to the battery and makes impossible to fit any battery into the battery compartment. ... But other than that, ... is an awesome diagnostic tool to have!

If you're a professional Auto technician or a do it yourselfer, this is a very inexpensive tool that you should have in your toolbox. I have used it several times and it's saves me lot's of time in finding a broken wire in a harness on vehicles. Takes the guess work out of wiring shorts and faulty wiring harnesses. The sound is adjustable "handy with ambient shop or vehicle noise" It's accurate, easy to use Led is bright and easy to see . Pays for itself the first time you use it. With late model vehicles basically being a big computer with many electronic controls in order to operate everything in the vehicle, on a broken wire of any length or a short can make it hard to diagnose a problem, A good scan tool might not discern a a break in a wire or harness, and show a code. So this enables you to find out why your getting a fault code, when the real problem isn't the sensor or control, but the communication from the ECM to the control due to a break in the wire. This company also has a large line of great testing equipment to work with this probe. You owe it to yourself to check them out. I made my purchase on Amazon, so if I didn't like the tool or had a problem with it, it's no problem because I could have returned it. Sorry that I didn't take any photos, but the instructions that come with the tool are straight forward and easy to understand. Plus there are videos on you tube and such on these tools. Hope that this helps you out. Keep spinning those wrenches and making $$. God Bless
