Great handheld scan tool!
Nice small scan tool to keep in your vehicle. Menus are quick and easy enough to navigate and it comes with all the functions you’d expect from a basic ob2 reader. Can check codes, clear codes, and view live data. Comes with a carry case too to hold the scanner and cables for the battery tester. Only downside is not being wireless but for the cost and use case it’s worth keeping one in your vehicle!

Great tool
Really needed the tool works great

Very good, except you can be tricked into erasing codes in the car while trying to read them
I didn’t give it a 5 star because the first thing I did was erase the freaking codes. The “erase” option needs to be further down the menu option, not the fiirst freaking option. If I click Read codes, don’t ask me if i want to erase codes as the first freaking question. I thought it was going to clear previous codes ON THE READER, not the freaking car. Now the dealer says they don’t know what codes were there and I have to wait until they pop up again. The dealer says they get that all the time

Perfect scanner that doesn’t break the bank

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.

Simple and easy to use
This is a very simple to use system. I have never used one before and I was able to watch a YouTube video and then put it to work immediately. Money well spent for years to come.

Excellent scanner
This thing’s great: clears codes in my car with no problem at all — in fact, if the car throws a fault while I’m driving it, the passenger can clear the code on the fly — and it gives quite intelligent suggestions as to what might be causing faults (e.g. “Faulty MAP sensor or leaky intake manifold gasket”).The buttons are a bit strange: you’d think the Select or Confirm or Enter button would be the big one in the middle, but it isn’t: it’s the little one over in the corner — took a minute to figure that out — but having done so, I had no problems with the user interface or the embedded function set, which is richer than anything I’m realistically ever going to need.
