Cheap and does do what it says it does. Will allow you to control all the sensors and lights on the vehicle if you have the add on for that manufacturer.
Vident iLink400 review 2:
For what I need to use it for it works well. tool is easy to update. I dumped the software for GM into the tool. was easy to do. the sard reader that comes with the tool is a piece of crap I have my own micro sd to USB adaptor that is much better than the one in the kit with the scanner. I have used it a few times. I wish it had a broader reach of abs/sir trans and ecm data it’s hit or miss whet it will read and not the same on every vehicle.

Used Vident iLink400 to perform an automated brake bleed on GM and exhaust system diagnostic. Creating an account and product registration are a chore.
Vident iLink400 GM review 4:
I recently replaced my Throttle Body in a 2011 GMC Sierra and had gone through the entire relearn process with no success. Drove for days with extremely high idle and acceleration issues. Finally took a gamble and ordered Vident iLink400, hooked it up and it was fixed in 2 seconds.
