This is the worst product I've ever bought from Penguin. Hands down. First, I could not get the
prep to work at all. Tried quite a few times, changed materials, tried some more, but no go. You
can't do this without the prep. If you could do it, I'm sure you'd find it VERY angly. And, no,
you can't hand this out. The prep would be obvious to anyone who got their hands on it. But since
the prep doesn't work, no problem. No one will ever examine it. No one will ever see me do it!
Pretty lame teaching, too. I'm really surprised Penguin released this.
