nitrox is not neccassarily bad. They support our forum, and ive bought from them before. The owners's name is justin, he is a physics student in college. he does decent work, good solderer on all his homemade stuff. The problem is some stuff is a little steeply priced for hobby classed work. then again, you gotta realize that companies are supposed to make more profit then hobbiest like on this site.
the green lasers featured on the cite are most likely chinese brand ones bought from a retailer. they will work, but the build quality is much inferior to optronics. If your looking for a cheaper investment, just remember, you get wat you pay for.
