TopDiag P200 Automotive Circuit Tester, (2024 Newest) 9v-30V Power Circuit Probe Kit with 0~5V Power Supply Fuel Injector Relay Mode, Car Electrical System Test Tool AC/DC Digital Voltage Short Finder

Decent quality and measure accurately against my other meters.

It does what it says and does it well.

I did the update from their site and you are left with the proverbial brick. But I searched hi and low and found the update file. Why the" manufacturer " hasn't got the correct file? Who knows. Dont update. If you get stuck I might be able to find it for you.

This is a great piece of kit for diagnosing electrical problems and testing sensors, it has a feature to download software for updates but my PC doesn't recognise it when I plug in the USB cable. Tried contacting the maker but the e-mails keep bouncing back, I'll ty again early January and hopefully resolve this small issue.

This tool is rubbish, frequently misleading info, I'm an Auto Electrician of 45 years and this is a poor example of this type of tool

Excellent diagnostic tool

Worst purchase ever. Stopped working just after a month. They don't pickup the call and even don't reply the email for warranty claim.

Product functions are good. I like the 5v limit supply and component activation mode. However the component activation failed to function on second use. Luckily still on return window. Item was returned.

I found everything I needed in this device

wiring not my strong suit al all normally lots of head scratching bowls of spaghetti mess what my wiring ends up like but with this tool you can make sense of the biggest of bowls. anything electrical this thing has a answer or setting to process or program for helping you untangle your or someones else's mess. good for finding dead parts with out the needless random part replacing stuff tell one something finally fixes it hundreds thousands $$ on down the road changing out perfectly good grade AAA parts for what ever you call the ones on your local bargen box parts store shelves needlessly. easy intuitive menus i didn't even need to you tube anything but i would bet if not already there will be some great learning content with one of these great tools. electrical isn't voodoo anymore now it is easy and !!!! are you kidding me 130$$$ (i thought too, way way to good to be true!) i have 0 to say bad about it and for me that is unheard of UN heard of. if i had to come up with something gun to my head or something little cheap feeling but no one is harder on tools then my i am the raining champion i am undefeted champ and i havent been able to brake it yet i will report back the day i do to give yall a update if it is just feels a little cheap or if it is becuse avrage 3 times a week 6 or of the seven last couple week so a fair bit have had it for a month now today it 6 18 22 ill let you guys know how long she lasts. are there any guesses out there?
