Ex Input:
Although it looks like a nice little product, I could do without the loud motor noise that is emitted. The unit would work fine if you didn't need to listen for it. It also is not very loud. I did test the suction power though by using my hand vacuum cleaner with which I got good results. All in all, I'd say its worth $17 as long as you don't mind being aware of sound when vacuuming.

Ex Output:
Bad review

I don't know what to say about this book. It's pretty much as easy and cheap with less than half the knowledge required. Don't waste your money on it! I recommend taking a class or doing more research....
