Query: Don't EVER use this book for intro physics

Our entire class has virtually thrown this book out and adopted other physics texts. While I am sure it covers the material, it does not teach you physics -- perhaps a good review text for those brushing up, but as an intro text I found it vague and obtuse. While I have never taken physics before, I do maintain a 4.0 GPA, and what little I have been able to derive from Lerner's text was hard fought on my part. Lerner does not address his audience effectively. He often explains theory as his only example of a concept, he does not provide nearly enough sample problems of the very basic nature, and the end-of-the-chapter problems are occationally so badly worded you cannot really tell what he intends his reader to solve. This text needs a very thorough editing before it can be a very good introductory text.
