Very bright light, strong light beam, helpful and useful in daily medical practice. Only drawback from my sight the holder made of plastic, if you constantly plug in the in the coat pocket, it is not safe, and I suspect that they may break rather quickly - Execution of metal would be certainly better ... otherwise looks pretty neat ,
Addendum March 2014:'ve just added an asterisk and ordered the 2nd lights for emergency medical service, support, despite my fears very robust, the 1st lights work properly and batteries still hold.
