Crosman Class II Red Laser

Pros
The most important thing to know and remember is that this laser is a CLASS 2 laser which is about the lowest power laser you can buy...less than 1 mW in the visible light range. Lasers costing around twice as much are CLASS 3 which put out about 5 times as much power (5mW). CLASS 3 is the one I want.

Pros
It fits all my picatinny rails except for the MK35, which I dremeled down enough for it to fit.

Cons
Not really found any cons. It works by turning the on/off in either direction. Mine works just like it should.

I've been buying a Lot of stuff from airgun depot lately. this is the first item I'm disappointed with. what do you expect for a $15 laser? probably won't bother to return it, cause i took the on/off switch off and broke some stuff inside there while trying to fix it. def. not made to be taken apart; it's hardly even made to have the battery replaced!

Pros
lightweight. compact.

Cons
P.O.S. could not get laser to stay on. the on off switch is total junk. loose electrical connections all over. turn it to "ON" then tap/bump it and it shuts off. slap it a few more times and it'll flicker and eventually turn back on. the negative battery terminal spring pops right out when you change the battery. tried 4 different batteries in it and that's not the problem. also, super hard to slide on to the picatinny rail. i can understand that you want a tight fit on there but getting this on my 1911 special combat model was a chore. ought to be tapered at the end to allow it to slide on a little easier.
