A keychain laser pointer has so many uses. These are very versatile tools that can, when used properly, be valuable additions to your life. 

The laser pointer does get bad press as young people think they are clever imitating the red sight on guns, which can get them into trouble and sadly if pointed in people's eyes can cause sight damage. 

However, when used properly for teachers and lecturers the laser pointer can be an effective presentation tool.

Some models have interchangeable heads which means that you can change the light to create different effects, such as a star shape, a thumbs up, or even a heart shape. These fall more into the fun category rather than the serious category. 

This is not an expensive accessory and you can pick one up quite cheaply somewhere. Amazon has a good range and they will deliver to your door. 

A keychain laser pointer can make an excellent small gift at Christmas, or just buy one for you to use in the lecture hall or in a business presentation. There are many uses for the keychain laser pointer, and the choice really is yours.
