I just bought one of these off of Costco's website about 2 weeks ago. I had it in my office window and nearly killed it over a weekend because it needs almost daily watering.
I abandoned the 'cool office plant' path and took it home and put it under my light in a huge window. It's doing great now. Already need to trim it a bit.
It's not really that well shaped, and has about a 1" diameter trunk. It's my first bonsai so I'm going to limit my meddling in it's life aside from basic pruning.
