When I saw the price I couldn´t leave it and bought one. Althought I have already one, this one has a little "normal" light also. So it is very handy if you give class in a dark room and just need a "little" light to find something!
For just 3 small batteries it does give a strong laserbeam. My other has a much stronger beam, but than again the batteries are bigger.
Real good X-mass gift maybe for other people?
