Thanks a lot for the info., I have checked the guide and would like to get a 1w blue laser pen from laserBTB, also I found another site selling the same power but price is lower, could you advise which site i should buy from? Thanks.
PL 405/445nm 500-2000mW
Briday B017 1500mW 445nm Adjustable...
So it's the same thing with the craps below $10 on ebay? The website says it's real 1000mw/3000mw/5000mw and it's blue not those green ones on ebay, i'm confused about the real prices for a real 1w blue laserpen.
So what's the reasonable prices for 1w and 2w 532nm or 445nm? Really confused with so much huge differences on pricing, I have been seen 5000mw 450nm price lower than $100 and 1000mw ones sell on $399 or more.
