Hi all,

Some time ago I bought set of 3 laser pointers for my wife. She's a teacher and needs them for presentations.
While Red and Green are OK, blue one is really weak (i kept that for myself). Dot is visible only on white and phosphorescent surfaces and barely on others.
No star wars beam at all. It reveals banknotes security features, but dot is too narrow, so it's useless.
Is anything wrong with it or I'm missing something out ?



Thanks
