I’ve used it in multiple places that I don’t like the questions. Hospitals when the tv remote has been “misplaced” (aka staff doesn’t give a fuck and someone stole it,) bars (with permission,) entry into hotel rooms, at my work because I forgot my badge.

And as mentioned, pen testing. Though not professionally and just at the office (with permission) to see how far it could get (surprisingly far actually, with the right badge.)

The thing about it is though, it stands out to an extreme. Even if I have it out on a table while sitting down (it’s rather bulky for a pocket) people take notice and ask what it is. “It’s like a universal remote” just raises more questions.
