What is a laser that is better than the 303 around 100mw and is under 50 dollars

Maybe try one from Sanwu---they actually test and meter the output + they get them from one of the better suppliers.
see: https://www.sanwulasers.com/product/304

If you want a actually good/excellent 532nm green laser best bet is Jetlasers here: https://www.jetlasers.org/index.php?id_category=17&controller=category

Sanwu says on homepage re: coronavirus lockdowns in China:
Feb, 13, 2020
New order shipping will be delayed until further notice(manufacturing suspend by China government due to coronavirus)
Expected Date on Resume to work: March 1

532nm 303's are a wonderful starting laser. I would really suggest contacting the seller and telling them it is defective. I had a problem with my first 303 types and they sent me two more for free lol
