well i mean i said things, but none of which were seriously bad, i havent flamed anyone. and ive tried to be helpful giving advice to people(with the limited knowledge i have). And when in conversation i like to give my side, just like everyone else.
a product called "goop" is nice to optics, a little fumey but the fumes dont normally adhere to things. i would test i before putting on your laser, ive had good luck with it.
mine has all those same problems, angled beam, flashing power (when i turn it on but its because my laser hops modes) . does your beamdot have scatter arouund it. i tried cleaning lens but no luck. im gonna live with it though. probably buy something way nicer when i have the resources.
wait you went to a garage sale and bought a gas laser. and people are just ok with that. where do you live that people just have gas lasers laying around for 5 bucks.
