Based on your expected use pattern, you should consider buying one unit (comes with 2 bottles) for work and one for home. Of course, this depends on your situation at work. I understand you might not be able to use it. They don't require power, but they can get loud (and stolen, I guess). Who knows? You might make some new friends though... The sugary flavors are garbage. The fruity "essential oil" type of stuff (probably the stuff you are drinking) are fine. Of course, YMMV, but I've had one going on 5 years now without a problem.
