Can the cheap OBD2 tools reset maintenance intervals, TPMS, etc? My perception was you had to spend a lot more to get scantools that would do that stuff. Newest car I've owned is a 2001, newest bike a 2009 and it was still carbureted, so I've never dealt with the modern stuff personally.

edit: and just to vent, I work on a family member's car pretty often and it's a 2014 - it has no dipsticks. You have to work through a bunch of menus and idle the car until warm before the dash will give you an actual oil level reading. I hate modern cars.

At the very least, it will prevent you from needing to pay the $35 OBDII fee that most mechanics have. They'll still use it because they never believe you when you say what codes yours spit out, but they won't be able to charge you for something you specifically mentioned when you bring your car in.

I have one and I make sure they can see it when I drop my car off.
