First, sorry for posting in this thread, but the others seemed to be very quiet and I only have a week to return my laser for a refund. I purchased this laser () from ebay with the understanding it was 2.5W based on the price point and the description in the auction. I have received the laser and it is 2.1W not 2.5. I contacted the seller and they are trying to argue that output strength of the laser can vary and is the reason they state 2W 2.5W. I have opened the laser and it contained the following lasers. Red 1000mw Green 300mw Blue 800mw Is it still possible/probable that my laser will output more than these ratings? Here is their full response to my question "It is real up to 2.1W , but like I said laser power is not stable, so we add 2.5 on the title . You can purchase another 2W laser light that marked 600$-700$ , compare their differences in eye , then make a decision. XDJ2000 is powerful , quality and large angle scanner , analog modulation . It is worth your every penny , and we offer local service , if you have a show coming soon , but light has issue , I usually help my customer to solve problems. I can give you one more week to decide refund or not . "
