I like it, but it's so cheap, what if the quality is no good...
e.g. the light stops responding to my taps after a while...

Hmmm.. just go shop around for items? Plants would be nice, but I
don't think small pots of cactus or dangling pots of money plants
would look very pretty. They're ok, just not the best. But I'm not
good with plants so I don't know which to buy... are there any
flowering indoor plants?
Maybe a nice cheery clock, some display items of your own... I used
to put a lot of anime figurines at my workplace...
Change the In/Out trays if they look dull..
Put a photo-frame on the table (kekeke)
