9mm 5mW Red Laser Module (3.5~4.5V)

Pros: Very nice laser
IT HAS A POT masive plus right there
Cheap
Good build quality
I maxed out the pot dont worry its a sturdy laser it wont burn out if u max it, it might get a bit hot
Very bright im guessing 10mw+ (with pot maxed)

Cons: The leads were really short and while striping the wire i acually cut it and now i have to work with a couple of mm of wire
but otherwise very good laser

Other: Good laser i recomend it

Pros: -Cheap -Does the job -Just like any common 5mw red laser dot. - it's potent you can use to point some things, or attach it to a weapon for accuracy, it has a lot of applications.

Cons: -At this price, i can't find any con. it's just a laser. maybe the terminals are more likely to be broken but.. you just need to take care handling them i guess... like any other component

Other: get it! i live in Mexico and it took them 3 weeks to deliver, that was fast.
