Blue lasers are on the cutting edge of consumer laser pointers. This beautiful blue-violet laser is more pleasing to look at than red or green! Please note, because the human eye is more sensitive to green than to blue, this laser pointer will appear less bright than a similar green one. However, the milliwatt output is factory-calibrated and accurate. In daylight or bright places, the blue laser will be more difficult to see. In darkness, it is still bright and perfect for use in presentations. In fact, it is not "too bright" to look at like some green lasers!
