I don't have it personally, but I do have his Precalculus review book and I like it a lot. It's well written, easy to follow and pretty much straight to the point.
I have the Simmons book in fact. The reason that led me to ask for others people opinios is that I saw some bad reviews about the book on amazon.com (although most of the reviews are positive), so perhaps someone who know this book and another good book on calculus could give an opinion of what is the best and why.
