Rated 5 out of 5 by from Love this unit! I am an application developer and work from home 50-hours per week. We get temporary outages (10 seconds to 4 minutes) on a weekly basis and my two INTERNET550SER's keep my laptop, 4 monitors and Internet connection up and running. I love these units. I can plug them in and feel confident that my equipment will stay powered.
