Q: The main thing I got out of this book was to take note of the difference between a'market' and what an artist thinks a market could be. While the writing is fairly competent, it can not be taken as completely self-serving. It seems to suggest that if you give them enough money they'll keep coming, but they won't. There are some interesting ideas there, but they're scattered amongst the clunky writing.

A: Bad review

Q: This lamp does work. A little tricky on installation, but...works. Unfortunately it's not as bright as you would hope. Not a terrible light.

Q: All this machine can do is shred paper. The shredder blade stops short of the stack every time and you have to shake it or pull out some paper manually for each piece which takes about 5 minutes. The shredded items are always larger than I need even after 1 inch. If you're making a pile over 1" or so, then use your hand since there was no safety guard that came with it. Do not attempt to crush more than one sheet at once, it's impossible.
