The power of the laser is excellent but thats only when it works properly. I don't think this laser is built properly. It's a shame really, it works when it wants to, the laser gets weaker when it wants to and then starts working. It has a mind of its own. I know it is not the fault of my batteries as I have tried many different brands yet the problem still persist. The only way I can get it to work properly when it is not, is to bang it with my hands, yet this does not always work. Overall, I think that the power of the laser is great and is very visible, however it has many flaws with the way it was built, I would not recommend these.
I bought this for use at work, as an alternative to the usual small red laser pointers. I generally use it as a pointer and to create a focus point when taking photographs in dark areas.
Really good bit of kit which runs on 2 AAA batteries and produces a great strong beam of light with a great range.
Would definately reccomend it at this price.
