I have long preferred the idea of an Air Duster over the cans of air that you can get, and I've tried some in the past with so much disappointment. Usually they seemed to be a gentle spring breeze, this is a decent autumn gale! and manages to blow the crud out of my PC etc quite nicely! (as well as blowing things off of my desk - Lego models and even a mug!) You turn it on by long pressing the button, and then using the slider you can adjust the airflow. Another feature that I like it you can make it suck! Pressing the button 3 times reverses the motor's direction making it a little vacuum cleaner. The tools are the standard ones but at least they stay in the duster unlike some I've tried. For some reason this also comes with some cleaning clothes, I mean I appreciate it and I guess it's something you'll be using it for, it just surprised me. A final thing that's included that I like is that it comes with a bag, just a handy place to keep it and all the tools.

I can't currently say what the battery life is like, since I've only charged it for a couple of minutes to make sure that it's working.
