Necessary purchase
In order to continue use of my MP3 player, this was a critical item. The new battery is working fine, and the prompt shipping was very much appreciated.

Rather technical treatment of the subject, but provides new insights into the sleep/wake cycle.
2 of 2 found this helpful Still in the midst of reading it, but hope it helps with my sleeping problems.
One disappointment: I inadvertently ordered the eBook version, whereas I wanted the paperback.
It was my oversight, so I am coping with the inconvenience.
