Very cheep. Easy to connect. 5v supply easy to integrate in a circuit. Good pointer dot. Does not get hot. Does its job xD. Very good for microprocessor interfacing. Low power.
Laser pointer not aligned properly with pcb and the dot is not a straight line. Pcb contact and wiring are all bare, can be easily short circuited.
great item !!
If you need a cheep laser device this is way better than building the whole circuit for a laser diode, which in 99.9% of the cases would result in a higher price, more complicated design, more components and more time... more money... so BUY IT
