    The only thing I worry about in that description:

    ● TTL Modulation: Optional,1-10KHZ or higher. If request,Higher rate up to 40KHZ available ● Analog Modulation: Optional,1-10KHZ or higher..0 min when 0-5VDC signal input
    So which Option is included, or are they made to order?

    I bought one of these a while ago. As of yet I still haven't been home. I should be back at the weekend to unpack all my goodies I've been ordering. I've also got a blue that I got from Dream Beamz waiting for me.

    I'll let you all know how the red from snoctony works out. Hopefully good !!!

    Cheers

    Looks like it has a beam like a postage stamp... A lot like the 635nm I currently have. If you get that beast and are looking to get rid of your 671nm let me know.

    Thumbs down

    I have one of these errr 'lasers' and I was less than impressed when I fired it up. In fact, I laughed...

    It is very bright and a nice colour, but the beam quality is shocking !!!

    Over about 10Mtrs the beam was about 80mm wide by about 20mm high... That is from memory. The laser is at a friends house at the moment, I will try and get some pics at the weekend..

    Another PL member (Rfourt) had one and he had a similar beam profile...

    You would get a better beam out of a 635 and only need half the power...

    Oh dear this doesn't bode well. Looks like I may need to look at getting a new red from what people are saying. I'm guessing I won't get a refund. DOH!!!

    I'll find out what my beam specs are like tomorrow.
