4. XTool D8s
I have been very pleasantly surpirsed with the Xtool D8s and it seems to be go-to overall OBD2 scanner in middle price range. For about $500, you will get access to topology module scanning, bi-directional testing, coding, unlocking features and using large library of service resets like oil reset or odometer adjustment.
XTool D8S
Service procedures are working better on Xtool (D8s) than in other OBD2 scanner brands.
I was able to use stuff like odometer change, airbag module repair, oil, tpms resets and others with both XTool D8s but also with similiar XTool IP900BT.

Mucar 682
Great alternative to Mucar 892BT or Thinkscan 682BT if you still want scan tool with free lifetime updates but you don’t need that advanced device.
