Worth it, very easy to use
Works great on my 2004 hyundai. I had a check light come on as my battery had to be recharged. After disconnecting the battery for a full recharge the check light came on for a misfire. The codes I’m interested in are the ones dealing with the emissions. I drove the car around doing errands and to reset the computer. I put this tester on the and checked the emissions, everything was green so I went to smog station and the car passed. Nice product as it has the capability to remove codes.

Good Product
Was delivered in excellent condition and on time. It wasn’t quite as I expected, but I’m sure it will do the job it is intended to do.

Good value and quality
Quick delivery…. Very professional looking tool…. Used it to check my batteries on my Duramax and it was easy to use and understand the instructions. Haven’t used the other functions yet. Will be a bit of learning to understand all the abbreviated functions. That’s what YouTube is for….

Worked as or better than expected on a GM / Toyota / Subaru
Used it on 3 vehicles and 5+ batteries.. correctly identified an unhooked dead battery and another one hooked up I knew was on its last leg and said ‘replace battery’. Pulled codes from all vehicles (one I already knew the bad code from dealership and it was correct.. another it identified the issue on we were trying to track down… already worth its weight in Ethereum.

Seen a few of these over the years, some give basic information (a code you can look up on line) and some with a bit more detail.This one gives quite a bit of detail from code for the problem to actually identifying what the problems could be.Easy to use, literally plugged in and it started up, menus are easy to use, and you can clear the fault from the system after you sort it, or in my case the problem had cleared itself (had a miss fire after putting a fuel cleaner in), but left the engine light on, of which is all I had to do was to reset it, which would stop the £80+ a time people seem to have to pay to get errors cleared with no real diagnosis from the garage as to why.Obviously if it happens again (which could mean injector or coil problem) I will take it to get it checked at a garage, but no matter what, it’s paid for itself already.

Amazing device. Works perfectly well once you get used to it. But very careful of the pins on the scanner so u don’t damage them. I almost damaged mine but it’s all good now
