    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:This is a much brighter laser pointer module than you would get elsewhere. Perfect for my application. Has adjustable focus, which lets you make the laser dot a bit larger if you need to. Works directly off a 5 volt source. I haven't taken it apart to see if i... Read more

    Involvement:General (knows how to use it) - Ownership:1 day to 1 week Pros:The laser can be focused to produce a dot. Mine work fine with 5v from de Arduino ( mine : arduino nano 3.0 ) without any resistence. The focus is made of plastic but works very well. I have focused it to 15 meters. Cons:none OtherThoughts:The body of the laser is made of... Read more

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:A great toy for the money. Outstanding build quality. Beautifully polished. It is possible to control the collimator. I set it to the desired location (grenade launcher in pistol), adjusted to the desired range collimator (30-50 m), shut it in casing and every... Read more

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:Good price, small size, easy to tear apart. It's a perfect host for any 5mm laser diode, you can pick up any PHR, long open can red, or any diode you want, rip off the old 5mW diode and put your one there. focusing is good, acrilic lenses doesn't look to be AR...

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month Pros:It is fairly cheap and all I wanted was the module. It is fairly bright, for a 5mW, in the dark. I even powered it straight from an Arduino pin without any problems so far Cons:I had one where the focus ring kept falling off when I would try to adjust the focus. It's no... Read more

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month Pros:It is fairly cheap. Focus ring is decent enough and works. I was able to focus to a dot of around 1 cm in diameter at ten meters. It is bright in the dark. Can be powered and controlled straight from the Arduino. Cons:It looks rather cheap. OtherThoughts:Shipp... Read more

    Involvement:General (knows how to use it) - Ownership:more than 1 month Pros:Easy to use. Easy to focus. Cheap. Used for many months. Small size. Runs cool. Cons:Casing is a little wobbily. Feels cheap. OtherThoughts:Used as part of a reflectivity sensor. Power output seems to be rather stable. For folks in singapore, the lasers' power rating is... Read more

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month Pros:Easy to get in peace, removing the 5mw diod was a peace of cake with the right tool. No need to heat it at all, Just remove the laser lable and twist the two part to get asses to the 5mw diod module, They is a fair bit of silicone inside but no big deal. The f... Read more
