This is my first laser pointer. It says 5mW and comes in a pen host which takes 2 AAA batteries.
Since its 7$ approx, I was not too worried if its less than 5mW, however, its clearly more than 5mW.
Reasons I think so
1. Beam is visible(not very much though) in lit rooms (CFL/Tubelight).
2. Dot is clearly visible on a wall 10meters away even in bright sunlight.

The host is simple pen host, however the build quality could have been better. The AAAs rattle inside the pen, and you need to insert some paper to stop that.
I tried a video with cell phone, but beam is not visible to the cellphone camera, because its not that strong.
So I took a simple face/nasal steamer(costs 350 INR here), and shone the beam through steam

I figure I can use incense (1-2 INR a stick) too.
This laser should be about 10-15mW, but definitely not higher, as I think 30mW+ overspec lasers can actually burn stuff. This does not.
That said 10-15mW is dangerous, and I take care not to shine dot on non matt surfaces.
My primary intended use is star pointing, and the beam is highly visible at night.
I would give a definitely "recommend" rating for the price.
