The beam really is very bright. Although I don't own an optical power measurement device, I'd say that it's putting out quite a bit more than the promised 5mW. As others have said, the wires are soldered quite badly onto the PCB and they let go quickly. The button is rather inconvenient too. But since ... Read more
- Power output
- Driver circuit This laser module is cheap, in my country it's about 1/6 of common price. Power output is very good, beam can be easily seen in the city at night, very bright dot at day, even under quite strong sunshine. Did not measure the real output yet. Construction ... Read more
Well, it's green, is quite bright, focusable, and arrived in one piece -- a good start by all accounts. 250mA appears to be the correct draw for this item (see further comment in 'Cons' section however). I have an issue with the description of ALL the green laser modules, though this one 'appears' to ... Read more
nice green laser , you can see it at night
quite a nice price. but is is chinese quality so its a good idea to buy more than one! leads tend to drop of , so you need some soldering skills to make them work. i also thought that the button on the laser was a bit annoing. also its a bit of a shame that ... Read more
Very nice laser module! I am use on I=350ma output power less 50 mw bright, low price Great module. Fairly well built. It's nice to have the option to put an on-board control on it, but a button makes it more of a "pointer." Great for DIY applications. If you can't even solder, this just needs ... Read more
Very powerful, considering the 5mW rating. Able to faintly make out the beam in a lighted room. The dot is clearly visible on the hillside out my window ~0.5 mile away in the late afternoon/evening. Very poor soldering. The wires aren't actually soldered on, they are basically glued to the module. The ... Read more
Seems well built, and very bright for is stated 5mw output, which suggests it may be doing even more.
- Small, and I mean quite small. it is a lot smaller than I had expected it to be.
- No power fluctuations.
- Adjustable focus.
- Reasonable price. Could be a little cheaper.
- Was backordered for quite ... Read more
The price and brightness. I use these for building laser vortex's for halloween and these blow away the ones I used last year be gentle handling these...build is not as sturdy as the ones I used last year but could not pass up the price. need to figure out how to replace the on/off button to be always ...

This laser is brighter than my 10mw green laser from a different supplier it works well with 2 rechargeable AA batteries. I could add a different switch easily without taking off the one it has.
It is so cheap you can afford it easily and if you kill it not a huge loss at the price. The circuit board ... Read more
