I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Why? Review writer does not like the book because it was boring, therefore it is a negative review.

New input: I like it. I live on the west side of the Cascade Range in Oregon and things get dingy pretty quick. I had my vehicle, the rain gutters on the house, landscaping bricks along the path around the house, and odds and ends all washed in about an hour. It works great. The only drawback that I can find is that it doesn't appear to suck up any cleaning solution in the high pressure mode. Only the low pressure. I haven't tried the upper tank yet so maybe that's the problem. Not a huge issue since plain water pretty much takes everything off anyway. The plastic double male hose attachment was a concern before I purchased the unit. I'd read that most of them broke pretty quick. As long as you are aware not to stress it out dragging it around, it will probably last a good long time. If it does break it should be easy to replace pretty cheap. Again great unit so far.
Solution:
Positive
