Rated 5 out of 5 by Excellent product/ excellent customer service I have had wonderful success with the UPS 550VA. I had what I thought was a problem and called customer service. The error was with our purchasing department not verifying the amount of wattage we needed for the battery back up side. Customer service went over every item we had plugged into the battery backup side and within minutes found that there was too much voltage plugged in. I was able to immediately fix my problem. Thank you to your customer service for friendly, and prompt help. My Tripp-Lite works wonderfully. September 23, 2013
Rated 5 out of 5 by It's there when the power fails. What I want of a UPS is that it be quiet, unobtrusive and there when I need it. This UPS does that for our workstations. September 9, 2013
Rated 5 out of 5 by Great product! Just set it up nand forget about it. Very easy to set up. You only have to follow the instructions to perform the required downloads. It has prevented computer damage due to small power fluctuations that would cause my computer to shut down. It also safely shuts down your computer if it is left unattended during a sustained power outage. A very valuable feature is if you have have phone service through a cable company you can maintain phone service for a long period if the power is out in an emergency situation. September 5, 2013
Rated 5 out of 5 by Saved my modem, router and alarm monitoring modem Prior to Hurricane Ike our power was not the best, after it was horrendous and I lost several devices due to surges. I invested in several Tripp -Lite 550U's and I haven't lost anything connected to it in 2 years. I have no doubt they have saved my devices several times during power failures and surges. An added bonus is after the generator (installed due to the flaky power) fires up I don't have to wait for all the devices to boot up, they ride through it without a hitch. September 5, 2013
Rated 5 out of 5 by Valuable Product To date, this product has provided the protection as advertised. This includes going through several power outages.Thank you September 5, 2013
Rated 5 out of 5 by Could not do without this product! Colorado has the second most lightning strikes in the United States (Florida is #1). Power outages occur quite frequently and used to cause panic. With our UPS's we don't have to worry about losing a day's work any more! September 5, 2013
Rated 5 out of 5 by Affordable and Reliable This product works for me at home every time the power goes out.I don't ensure that my PC stays running, but my internet modem, and wireless router, always stay up for longer than the outage is, saving time and connections. September 5, 2013
Rated 4 out of 5 by Good product I got this product due to TrippLite's reputation. I didn't realize it didn't have a replaceable battery, but it's lightweight, and very functional for basic use. March 26, 2013
