Not what I wanted
Can’t leave it plugged in. It drains the battery
Giuliana –
Worth more than what you pay!
This product worked exactly like it says it does! There was almost no set up in the app (which is completely free) and shows you just about everything you would want to know and more. The scanner is small, making it easy to store in small places. The app design a great design, it took me a second to figure out everything and what it did but after that I’ve had no problems! Gives you options to read and clear codes (if your car allows for DTC code clearing)

This is great!
I have an older code scanner, but decided to try this one, and I’m so happy I did! It’s much easier to use and has many more functions. The battery voltage feature is nice, too. This is an excellent value, and I would definitely buy it again and recommend it to others.

Not the one….
Was able to read the codes but wouldn’t erase them. It took a lot of extra effort to even read the codes. A cheap unit at Walmart read it better….

I can just stick this OBD II scanner and forget about it. The area underneath the driver’s side is a crammed space, so I appreciate the fact that I don’t have to bend all the way down to access that
