I was going to give it 4 stars before I learned how to get the alarm to keep going off even after the lid was shut. Because that's what a thief would do first if they wanted to steal my laptop while I left it unattended in the library. But now that I know it will go off no matter what the person does (I set it so that the alarm shuts off once the movement stops...AWESOME!!) I love this. Seriously, for a free product, the quality, design, and the user friendly controls set-up is simply astonishing. Keep it up!!
