So I just got a 532nm 303 and a 650nm 301 laser and while the 303 is working perfectly I'm having problems with the 301. Basically I want to focus it into a small dot but the focusing lens is causing a bunch of problems. It moves around and rattles even though my 303 is fine. Is mine just defective or is this just how 301's are?

Those 650nm laser diodes in the 301s are not really focusable to a small point which is what you would need if you wanted to melt plastic or light matches on fire. They are just interesting little pointers really.

Cron, are you sure the knob or knobs is tight to the lens barrel that it's suppose to turn and focus? That will cause slop.. I say knob's as i'm not sure it has the extra star cap feature..
