This USB ashtray is probably the most useful development since the invention of computers and smokers. Finally the scent of cold fags is eliminated right where it comes from, in the ashtray itself. The combined carbon filter/ionizer is also able to reduce the smoke coming from a cigarette and it can even filter other disturbing scents in the room. Using the ashtray is easy: Just connect the USB plug into any USB port, the USB ashtray will start filtering the air right away. And it even looks funny.
