Excellent product, easy to read without glasses, works on every type of battery and does not require any additional power source other than batteries. I use it with a small LED flashlight for all kinds of things including checking my golf swing. The LED is much stronger then the old flashlight. A plus is that I can clip this device anywhere in place which makes clipping or removing your shoes even easier. If you need a great reliable wireless device, get this.

Good Review

Bought from AMAZON for my mother and they work great. They sound clean no noise when playing CD's.

As a lover of this book for years I would say it's great if the content is as well organized and written but to me it just wasn't what i was expecting from such an important figure. There are other biographies out there that do a better job explaining some aspects about his life and times so you may want to hold off on buying this one until you know which version you're looking for. It doesn't tell all there is.

Good Review
