I ordered one of each color (red, blue and green) in the default dot version. I was looking for three similar ones to use in my project and getting three from the same vendor was an ideal find. Blue laser modules are very hard to find, where I encountered the offer. Also often blue pointers are 405 nm, which leads to the blurry purple look (if not used with white paper that gives fluorescence).
This one here had a wavelength that seems to be around 450 nm (without having double checked that), that leads to a well defined nice blue laser spot.

The price was good and the quality holds up with it. The small boards are in metal (aluminium) cylinders, where the chip etc can be easily accessed.

One small "issue" that I encountered was that the red module came in a longer cylinder, although being fully compatible with the other two (being also slightly heavier). So I got another one to have three fully compatible modules.

In terms of power / brightness. The green and blue look similarly bright, while the red is a bit dimmer (still bright enough). Likely they have similar powers but based on the detection efficiency of the eye, they appear differently bright.

At full power the green and blue are a bit too bright for my taste, so I would either electronically (with a pulse width modulator) or optically (using ND filters) regulate them down. The red brightness is good even without it. To highlight here, that is great. It is easy to lower power, but hard to squeeze more out of them.

So a clear recommendation if you are looking for a laser module.
