Recommendations for OBD2 Scanner

For those that own a OBD2 diagnostic scanner, which one do you have? I need to pick one up and trying to decide between a self-contained hardware device, or a Bluetooth adapter that integrates with a phone app.

The OBD2 bluetooth capabile devices can often be accessed by other apps from other companys.

Read reviews. My Sister got an adapter which seems overly complicated to use.

I bought a BlueDriver OBD2 scan tool back in 2018.
