I have had numerous surge protectors before and they have all worked okay, but I have never had one that also had a battery backup as well. When I saw this one, I wanted to get it because I have a lot of work that I not only want protected again lightning surges, but also, if the power goes out, I don't want to lose my documents.
Some things I really like about this battery backup/surge protector is that there are plenty of outlets (8) for plugging in all your office plug-ins. Each of these have surge protection and four of them have the battery backup. If the power doesn't come on after about 45 minutes, the software that is included with the surge protector slowly shuts down the computer for you so you don't lose your work. There have been several times when the power has gone out and it's been nice to be able to continue working.
