Query: Junk!

I own two other Adesso lamps that are substantially similar to this one. And since I'm satisfied with them, I thought I'd be satisfied with this one, too. No such luck! Adesso's quality control must be essentially non-existent, since this lamp (which requires assembly) arrived without a knob for the on/off switch, and the three pieces that are supposed to screw together to form the column...well, they don't go together properly. So instead of being upright, the lamp has a slight...but very noticeable...kink in it. There's no excuse for selling a trusting public trash like this. Adesso should be ashamed! They are absolutely off the list of vendors I'll do business with.
