What Customers Are Saying

Customers are divided on this diagnostic tool. Many praise its affordability, ease of use, and ability to read codes, clear check engine lights, and display live engine data without requiring a smartphone—helping them avoid costly repairs. However, a substantial group reports serious frustration with software updates and registration, citing serial number validation errors, broken download links, and Windows-only support that leaves other users stranded. Some note build quality feels cheap, with USB connection issues and small display text. Despite strong capabilities, unresolved software problems have led several customers to regret their purchase.

Garbage

Would Not Recommend

Scanner works well but print function is junk. I downloaded the software update as instructed but scanner says I need to use a newer version of update tool. The print function is very important with OBD2 scanners. Very Frustrating!!!

Total crap.

Software update is FUBAR! Keeps asking for a 'Register Code'. I tried every number on my Lowe'sw receipt. Every number on the box. No go! Nothing works. What is this magical 'Register Code'?

Absolutely no instructions on how to operate said scanner tool. No additional instructions on line. Not even vague instructions describing what button do what. Garbage scanner.

[This review was collected as part of a promotion.] For being a cheaper reader, I'm fully impressed with the features and and how well it performs. For the diy mechanic, this is a must have.

Does not work... period!

Would Not Recommend

Bought the scanner, went straight home and updated the software with no problems... however, it only works in the vehicle if you use the USB plug. ( It should power up from the OBD2 but doesn't.) So I use the USB plug provided, power it up and go to diagnostic... and it says Entering System but never does.

Nice Reader

Would Recommend

Being the nerd I am, I plugged this in as soon as I got out of the store. Awesome information; I was totally impressed until... I brought it home and plugged it into my laptop to see if there was an update. Review the following screen-shots for what I saw. After changing the defective USB that came with the unit, poof! all problems vanished.

Had to update to possibly get it to work. Couldn't download software update at first, I finally did update hasn't worked. Used two brand computers to download the software and still haven't got it to work. I am returning the item when I get back to Lowes
