Tripp Lite INTERNET550SER 550VA UPS Compact Low Profile Standby 8 outlets w/ DB9 Port
We have been using our Tripp 550SER since October 2008. It meets our expectations for a great surge and small back up power supply. It would be nice if there were an option to turn off the beep alarm when the standby power is running.
This is a great unit.

Originally purchased a similar product by Trip Lite five years ago for another computer and it is still working fine. Therefore, buying this UPS for an new computer was an easy choice. In additon, the compact size is a plus.

I've used this battery backup for less then a year and it no longer works. When the power goes off, so does everything plugged into this Tripp Lite battery backup. THEN the battery backup kicks in and starts beeping. Real useful. Total waste of money and could ruin your expensive computer equipment when you think that you are being protected from power surges and outages.

This unit failed 2 months after purchase. The surge protected side lost power and would not reset. I tried to get it replaced but got no response. So I replaced it with a more expensive brand known for it's reliability (ATP).

I bought this UPS back in May 2010. I had owned an APS UPS previously whose battery died after a few years, and had heard of Tripp-Lite's good reputation. Unfortunately, I don't know if I have a "dud" but it has lost power while the computer was turned "on" several times. I bought this UPS for the sole reason to avoid power outages while my new $2000 iMac is turned on and this thing is actually causing them. I'm in the process of contacting Amazon regarding a replacement. I must assume that this is an anomaly, so I'll try to post a followup regarding the replacement unit.

It has worked well. The beeping is to signal that an electrical surge has damaged the product (but saved the computer). We have several for the office and they allow us to keep working during short outages.

My office received four units. All units failed at the first power outage. The APC units worked fine, as usual.

The Tripp Lite battery back up is a complete waste of money. You are better off connecting directly to the outlet and saving your money. If that is not an option (likely the case) buy an APC. If the price is 2x or 3x that of the Tripp Lite, there is a reason why.

Can find no fault with UPS -- it sits there and does it's job. Have used it 24/7 for a couple of months with no problems.

No trouble out of this unit. Keeps me from any data loss. from power spikes.
