They are well made and are a great idea for low-risk areas like some suburbs' GO stations or elementary/high schools. I say this because the only anti-theft deterrent is not having a 5mm hex wrench which is essential to any bike multi-tool.
I recommend this for young students because if you have quick-release skewers which are more common now on lower range bikes than when I grew up, you can expect some "silly" students to remove a wheel or two and mess around, or try to steal it to be cool, that kind of stuff. They are neither sophisticated enough or willing to put it the effort to actually unbolt a wheel just to screw around.
Living in downtown Toronto, I don't think these are secure enough for the insane amount of theft I often see happening around but for the above-mentioned areas I think they would work just fine.
