They can lock you out
I have been using the Autel HT200 for three years now, but today after my phone paired with the HT200, it said the device is locked and couldn't be unlocked until a 'review' was finished. No information as to why. No information as to how long this would take, No number to call, No e-mail to send to; they just decided that I can't use this tool that I bought. That was not a happy exercise either. You pay for the hardware, then you pay for the specific modules you need at $30 a pop. This started out as a racket and now they are cinching the noose tighter.
