My 100mW Lasever blue did die after some use..
Dont know how old it actually was (becouse I did buy if from spec)
But I did just E-mail Lasever, sent them my blue to China..
Give them a small but not to small, amount of $$ and they did upgrade it to 200mW.
Including a brand new power supply with better stability
So the custom service there was just great !!
I personally think that the customer service is almost more imporant than a tight beam !
