We feel that, since it takes two people to even pull the canburglar from its rest position (and it has already been tested through the rigors of slamming repeatedly into an alliance wall to dislodge a stuck tote), it's a near-impossibility for it to fall and injure someone out of the blue. The hooks also rest inside our frame perimeter, despite an optical illusion that makes them appear far outside it, so there are no similar concerns of people standing up into them.

The only concern is to keep phones, computers, and buttons away from the magnets! My driver button was attracted to them, pulling my shirt with it, from around five inches away and I was convinced I'd gotten myself hooked on something until I looked more closely.

So you made your arms safer by instead introducing a pinch point that would destroy whatever appendage happens to get caught between them?
