First Alert 3040DF Reviews

Rated 5 out of 5 by from Very Practical We purchased this Digital Security Box for our daughter for her college dorm. It is the perfect size for her computer and other important personal items. Most computer locks only lock the computer, this again is great to secure other items without having to buy a separate box. It also attaches easily to her bed with the security wire. And you can't beat the price! I have recommended this to seven other friends for college and home use. Thank you for an affordable and very practical security box!
