As it was said, most of the people need the laser pointers from time to time, no matter if it is a 50mW green laser pointer or a more powerful green laser pointer such as the 250mW one for example. However, the truth is that most of the people do not pay too much attention on the quality and type of the lasers due to a very simple reason: they do not need them for something important.
What most of the people use a 50mW green laser pointer for is pinpointing text or pictures while delivering presentations, lectures, lessons and so on. Of course it should be mentioned that such laser pointers are also commonly used by the guides in museums who find them really useful. It is not difficult to come up with the thought that all those people do not need an extremely powerful green laser pointer because it would be just enough if its green beam could reach the particular object, which is usually not further than 20 meters away. So it is obvious that spending a lot of money on lasers is unneeded.
Furthermore, a cheap green laser pointer (or cheap laser of any other color) does not mean that it is of low quality. One of the main differences between the expensive and inexpensive laser pointers is the brand- the ones which do not have the logo of a famous brand on them are usually much less expensive. So it is really not worth it paying thrice more for nothing but a logo, especially when the laser pointer will not be used for anything that important.
It would be different if a powerful green laser pointer was needed as an SOS tool. People who love to mountaineer usually buy such lasers which will help them in case they got lost. There are really powerful laser pointers (such as the 250mW ones) whose green beam can reach 10.000 meters. And that gives a very good chance of happy end. It is not worth saying that this appliance of the laser pointers is much more important than the previous ones. So spending a bit more on a laser pointer is definitely a good idea because the more expensive laser pointer is usually not only a more powerful one but a safer and a more reliable one also.
