    Cheap, Bright, Works, Burns

    posted by messitom on 08/06/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    Small and fits into things well (host). This will burn when run on 3v (2 AA's) with the lenses removed. My wires were soldered on well. It IS focusable. Beam is visible in low light conditions and solid at night. I suspect (as others have stated) most of th...
    Cons:
    1 month ship time to US from time of order.

    50mW 532nm Green Laser Module (3V 11.9mm)

    posted by mustkivi on 02/11/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Ready to attach to power source. Bright enough to see beam in most lighting conditions. Small enough to fit into many types of enclosures.
    Cons:
    If you value your eyes, get some goggles that cover 532, 808 and 1064nm... or use a piece of heat absorbing glass in front of t...

    Cheap and powerful

    posted by zak4000 on 02/02/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:more than 1 month

    Pros:
    *Very powerful, can easily see the beam indoors *Current draw is ~400mA from 5V USB, ~260mA from 4.5V 3x AA batteries. *Much quicker to burn stuff when powered by USB.
    Cons:
    *Wires come off easily, but soldering them back on and adding a little bit of glue fixes that. *Transistor on the PCB gets hot ...

    Nice green laser pointer, works well

    posted by bamsoft on 01/09/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    The laser pointer is very bright and gives a good geen narrow beam. I used it to point out stars to other people which works very well. Tried out to project a dot on a wall at a distance of >500 meters and this worked without problem!
    Cons:
    The leads are too stiff. They broke off after bending them a few times. So i soldered some more flexible lead to the device.

    Pros:
    Ready to attach to power source. Bright enough to see beam in most lighting conditions. Small enough to fit into many types of enclosures.
    Cons:
    Limited focusing range, leads need to be re-soldered right out of the package. Not truly 50mW output. 50mW Input current wou...

    Awesome!

    posted by ffta123 on 11/30/2012 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week

    Pros:
    Easy to use/setup, can be focused, very bright, some burning ability. Great for doing F/X, general experimentation, astronomy.
    Cons:
    As everyone says, wires come off easy, but easy fix in 2 seconds with a small soldering iron. Be prepared to do this right away.

    Good laser

    posted by einyaa on 11/21/2012 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:less than 1 day

    Pros:
    Strong, round beam visible indoor in daylight. Easy to screw off two lenses in order to access the KT-crystal. Here is the beam very thin, and can burn plastic instantly.
    Cons:
    May be not full 50 mW green. Infrared light also present in output due to lack of filtering. Bad soldering of wires (the fall o...

    posted by mastertriangle on 10/18/2012 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    Very powerful for the price (I would be happy paying more) and the package size. The driver circuit is excellent and will maintain constant power over a relatively large voltage range. Beam can be easily seen at night even with a bit of moon poking out.
    Cons:
    The wires are crappy and fall off easily but new ones are easy to attach. The circuit board needs support if the button is to b...

    Powerfull green laser

    posted by lasermanathome on 08/06/2012 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Have bought 3 pieces. Quality of beam and power are GOOD Divergence can be optimised. Two of these lasers are TEM00 (95%) Beam is polarised.
    Cons:
    Watch out, infrared energy 808 and 1064nM is mixed with the 532green beam, the 1064 has the same divergence , the 808nM beam ha...
