When I received this laser module, my first impression is it appears very professional. It was packed in an anti-static bag with a laser safety sticker. The green laser line is very sharp at 5 yards, even can be seen outdoor. And, the laser line is perfect straightness. It was made from a direct green laser diode, not DPPS green laser, I was surprised it even worked below zero degrees without any problem. I used it as a guideline indoor open space without any air conditioner and it works fine all the time.

We had these running 24/7 for a few years before burning out. some of them are still going after more than 3 years!

The headline says it all. If you use it indoors, it's fine. But I wanted it to be much brighter.If you purchase the recommended "farhop" aluminum mount, you'll have to bore out the mount to 1/2". Aluminum is soft, and it's easy to size up the mount to fit the laser. In the pics, you'll see I attached it to a secure piece of wood to make it easier to hold the mount steady.

Images don't clearly show that it is about a 1 inch laser with two dangling wires, no connection or button or plug. The schematic is not clear either. They could resolve this by posting an image of the part in the tiny bag it comes in.

I bought the "user's also buy" mount to go with this laser. It was a 12mm T-block with 12mm hole and a bolt to clamp the hole tight "farhop 12mm industrial aluminum...". The laser says 12.5mm diameter which is a tad under 1/2". I used a 1/2" twist drill to bore out the another .6mm (1/2" is 12.6mm) and the clamp works just fine.

I have purchased 5 of the VLM-520-27 LPA round brass body green line lasers. All where packaged well in an anti-static bag with labels. I tested these lasers in comparison with each other using same 8.4vdc Li battery source. Differences are relatively indistinguishable in brightness, focus/distance and line clarity/sharpness. Two of the five lasers seemed to shift towards shorter wavelength producing more greener color than the other three. All lasers drew approx 70mA from same source and had very minimal (if noticeable at all) beam artifacts. I feel these are actually much better in terms of function versus the more expensive and slightly finer VLM-520-37 LPA with a precision square body.

The unit would operate fabulously if it is being used indoors. Unfortunately it is not bright enough to use outdoors, even in the shade. It just is not powerful enough.
