I have to agree with the other one star reviews. After a few uses all the digital gizmos and the torch stopped working. It still inflates but I have to use a separate pressure gauge which is inconvenient to say the least. Definitely one to avoid.
I remember the killing of the Kennedy brothers and Monroe from my youth but I had never bothered looking into the background, simply accepting the 'official' accounts of events. After reading this, what seems to be a deeply researched, almost academic, account of what happened I was amazed by the true story, which is quite frightening in many ways. Well worth reading.
