“wow, give this scanner a try!!! I am so far from a mechanic is ridiculous but i have many older vehicles and i figured i woukd try this diagnostic scanner before getting ripped off at a dealer. . Well it is extremely easy to use, it will clear those nonsense “”check engine”” lights along with some much other functions. I have multiple konnwei scanners, battery chargers, and diagnostic tools. They are all great. I can’t explain how easy they are to use. Try it!!! Lets go 🤟 👍

I really like its 5 special features, oil reset, tpms sensor reading, dpf regeneration, epb reset, and battery match. The key is that it is very small, easy to carry, and can say goodbye to my $500 large screen diagnostic tool!

My 2012 VW Caddy doesn’t show any errors. It connects poorly. Very few functions. The update doesn’t work, version 1.1 – no updates. Useless thing.

Looks good, easy to use. Presents well and with all the functionality this will be an added asset to my tool box.
Light weight, solid construction, decent cord length with a sturdy plug connector. Easy to read screen and very straight forward functionality.
Recommended purchase.

“no need for large pre installation fees.
Remove the diagnostic device and simply plug it into the obd2 interface to start using it. This device does not have a built-in battery, but operates directly through onboard voltage. Then bend sets the language through a simple and self explanatory menu. The operation is also understandable to every tenant.
I think the diagnostic and error reading functions are already sufficient for ordinary users.
I completely agree with the product description.
I give a five-star recommendation for purchasing.”

This is a really good little scanner for the diy or home mechanic. I’m not sure it would be a good fit for a full time mechanic, but it could work. It plugs into your vehicle’s obd2 port, so a bluetooth connection & separate device is not necessary. You can read error codes, check emission system performance & even read live data to help track down a problem. It is a sleek and modern design & was definitely a great deal.
