Rated 5 out of 5 by from Great product and great customer service! I purchased this product as an UPS for my cable router and NAS drive. It was working intermittently. I reported the issue to Tripp-Lite and they could not have been more professional. After trying a few things they suggested without success, they sent a new replacement that works great. New UPS, no-cost, no-hassle. Very pleased and would by another Tripp-Lite product. Their customer service cannot be beat!

Rated 5 out of 5 by from Excellent UPS / Voltage Regulation for my Pellet Stove I purchased this for two reasons - uninterruptable power and to ensure there are no more low voltage issues when the stove detects a brown-out situation. Very Happy with this purchase. I have several Tripp-Lite products in use and they have always work perfectly.

Rated 5 out of 5 by from Great protection Very good protection and features. Wish my NAS could monitor the status of the UPS via USB, but it seems to be an issue with the NAS and not the UPS.

Rated 5 out of 5 by from So far so good: no problems after 1 year. Bought one 1 year ago to back up the power to my workstation. Since then we have had several intermittent power interruptions with the workstation not noticing. So far so good. I purchased this one again to support the network infrastructure (cable modem, router and switches) but not installed yet. Too early in the use cycle to say whether I'll have problems later, so only 4 stars.

Rated 5 out of 5 by from Yes I would buy it again if it does as expected. I have only had this unit for a week but it seems to be very nice. It has 5 regulated outlets and 5 protection only outlets which is all I need. I bought this in order to smooth out the power if I have to use my gas powered generator. I have not had to use it so I don't know how it will do in that respect. The unit is compact and fits nicely between my computer and printer stand. Shipping was fast and the unit was well packaged and protected.

Rated 5 out of 5 by from A real life saver for someone in my line of work I use my computer to remotely manage IT infrastructure for other companies and three days in a row we had electrical storms that caused us to lose power for up to a few minutes. I ordered this Line-Interactive UPS and installed it and since have continued working twice during brief storm-related power outages. I've always used TrippLite surge protection but this gives me even more protection.

Rated 5 out of 5 by from I would by another one if I needed a second one. I have not had my Tripp-Lite UPS very long, but so far I like it. I use it as protection for my computer and other equipment. We get frequent blackouts, brownouts etc here. It seems like a sturdy quality product so far. I also use the power alert console along with it. It works very well, it is a java program so a little differant than a windows program, in the end probably makes it better though. The power alert console is great but manual could be a bit more detailed. A person without a lot of computer experience might have some difficulties with it.

Rated 5 out of 5 by from I Would Buy This Unit Again and Again! I bought the Tripp-Lite 750VA 450W Line-Interactive UPS. It is absolutely a 5 star unit. Installation was a breeze. I even installed the online software to manage my unit. From the moment I commented my PC to the Tripp-Lite and switched it on, I have felt totally secure from power outages and surges which happen in my location far more often than one might imagine. Absolutely 5 stars!

Rated 5 out of 5 by from Great for wifi, not for jacuzzis. Electricity is confusing! What model to buy! How long will it last? Can I use this to keep my jacuzzi running? (No.) This is a great model for keeping your internet running a good while if the power is out. Or you computer for a shorter while. Or your TV for...wait, nobody needs a UPS for their home TV. Read the manual to make sure you don't overload the battery and you will be fine.

Rated 5 out of 5 by from So far so good! Just got a new computer in a house with really old wiring. Not dangerous, just old. The Tripp-lite battery backup and surge protector is well worth the investment to protect my other electronic investments from unforeseen surge mishaps. The wall mount keeps it up against the wall with very easy access to all the plugs.

Rated 5 out of 5 by from I would not only buy this product but would also recommend For me the most powerful feature of this product is the AVR- Automatic Voltage Regulator. We all may take it for granted that the voltage in our homes is constant but all you have to do is use a voltmeter in your house hold plugs to see the variability through out the day. If you have any hi-tech equipment at home such as TV's, receivers, or DVR's you know the importance. I would for sure buy this product again and recommend it to friends

Rated 5 out of 5 by from Dependable Workhorse!!!!!! This unit is the 3rd. one in my Replacement of APC units over the years. It is a solid performer and dependable, always. The big advantage of the Tripp Lite products over the APC units, is their ability to function flawlessly during our frequent power outages when my system kicks over to backup generator power.

Rated 5 out of 5 by from The AVR is a REAL added advantage. I've had many battery backup units but bought this one because of the added AVR function. Seems to really reduce drop out going on battery. I rarely now go on battery but know my voltage fluctuated by other appliances and TV dropping out. AVR is worth it,

Rated 5 out of 5 by from I would definitely buy again I've been using TrippLite products for many years. My experience with their Isobars have save me a lot of money. Mountaintop locations of communications equipment, mine protected by Isobars. In all cases of lightning strikes entering the buildings via the AC line, the Isobars did their job in protecting my equipment, while surrounding equipment got fried. This happened on many occasions. I just purchased a TrippLite UPS, and I'm sure the reliability and quality will be there with this product as well. I wanted to buy three units, but the store had but one. ... Quality products that you can sense when removing from the box.
