Hi, a while back, around 3 weeks I purchased 3 lasers of aliexpress despite the negative reputation, but the lasers turned out to be pretty decent. I bought:
1. 250mW 650nm laser, actual output was 229mW $32
2. 400mW 405nm violet laser, actual output was 333mW $55
3. 200mW 532nm green laser actual output was 104mW but seller said he made a mistake, send 100mW model $55
Here are some pictures,
