Rated 5 out of 5 by from A nice, useful product. I use it as the battery backup for my Internet, WI-FI, and Computer. Nice to keep these up and running if there is ever a power outage.

Rated 5 out of 5 by from Abundance of outlets Helped to fit a lot of small, low usage devices on a single outlet. With plenty of backup time to last for a short power outage. If your using it on devices not using a computer you may have to check if it's compatible from the start. One odd thing... How to shut it off independent of it doing it on it own!

Rated 5 out of 5 by from This product does what it says it does I love my Tripp lite. It has saved me lots of money. Where I live we seem to have a lot of blackouts, brownouts, and surges. I have had to replace several computers because of this. Since I got the Tripp Lite My computer shuts down proper and I have had no problems. I would highly recommend this product to any one.

Rated 5 out of 5 by from My EC0550UPS has great features. I have been using my EC0550UPS for about 15 months and really appreciate it's dependability. It gives me plenty of time to allow a smooth shutdown after a power outage. I would reccomend this unit as a very good investment in backup power systems.
