I'd agree, but I did it at work in a conference room. And I was able to schedule a day out virtually instead of a month out for in person, and I didn't want them taking my fingerprint.
I used a spare laptop I wipe.
Making them surveil your employer instead is not a bad idea either.
I'd pit my megacorp's security against theirs any day of the week, but as I said I just used and wiped a laptop just for the test.
