I have model 350U I believe and I love this thing. No more downtime during storms and surges, it also includes a software that will shut down my computer automatically and safely when the battery gets low. I have had recent instability and power surges with my power and all I hear is a small *click* and the backup is on, I don't even lose my internet connection since I have the modem on it too. I love this thing, and the best part was that there was a rebate so I got it for only 50 bucks.
Just thought I would put up a post for those who are maybe looking at surge protectors/backups...I highly recommend a battery backup and regret not having one earlier.
