Hello! I am in the need of a good and safe laser pointer for educational purposes (I freaking love science, and I want one to do experiments with, I am 16yo). It'll be my first laser. After an excessive amount of research, I decided to buy a "Premium 4.99mW+ Green laser" from optotronics ( https://www.optotronics.com/proddetail.php?prod=Opto5 ). As I am an unlucky loser, I got unlucky again and the laser is "out of stock". I've tried to contact optotronics and ask when will it be available again through an e-mail about 5-6 days ago, however, I haven't received any response. I tried again yesterday again, no response. Tried today with a different e-mail account, still nothing. Do you guys know if something is wrong with optrotronics at the moment or maybe I should contact them in the other way (not a phone call, I am not native English speaking, I mean I could, but I really don't want to)? Maybe give up and purchase something else? I don't want to buy anything from e-bay, because, you know permanent eye damage stuff due to someone selling 50mW as 5mW. I was considering laserglow, but their shipping prices to Poland are absolutely crazy, I mean 70$+ for the slowest one, also their lasers are very expensive (like I said 16yo I don't have any income, also in my country 1$ is more expensive than 1$ for US citizens). Do you have any recommendations for good lasers or actually any advice would be amazing, I don't have anyone to ask for help, heck 90% of my "friends" (classmates, parents) don't know what a laser is (slight exaggeration, but you get the idea). PS: please point out my grammar errors, I'll be more than happy to improve. Thanks in advance.
