This lamp does work. A little tricky on installation, but...works. Unfortunately it's not as bright as you would hope. Not a terrible light.
Bad review

The book really didn't hold my interest. Not one of Grisham's best books. Hard going at times,and almost nothing on the death penalty. Too many things that did not make sense. Would have been better if he had concentrated on just ONE murder.
Bad review

This DVD is a big disappointment - I had high hopes for it being on sale and all. The material itself IS interesting, but the quality of it is......well. If you're looking at this item, chances are you are either already invested in his work, or just want to see one more film by him. And there was another version available, so maybe that's why mine is bad.
