When I look at things like this I see them more as designer safes as opposed to an old school one that is secured in the foundation of your house and then covered by a wood floor and a rug.

Just in general in a smash and grab it's a lot more likely to be found and taken then something that is a bit more generic looking.
And yes you can secure it to the bottom of a table but then why the tamper stickers. If for some reason someone sees it they might ignore it.
Ohhhh....a tamper sticker, I wonder what is inside of it......
