I bought two of these units to power and protect my TV, stereo unit, set top box and DVR whilst the second one powers and protects my security cameras and NVR unit. I am disappointed that the cooling fans are so noisy when the AVR is operating. Our power supply is quiet ordinary with the input voltage always around 130 or even a little higher. Hence tha cooling fan operating most of the time. The unit itself I am happy with with both the protection side and backup power. I had read reviews on other units and this one was suppose to be the quietist when running. If you can put up with the noise then I would recommend buying it.

I purchased this a couple months ago and have no complaints. I like the display and have important PC, Switch and Server equipment plugged in. It has bleeped once or twice when a surge or millisecond outage occurred. I usually buy APC but I found their batteries seem to die pretty quickly, regardless of overall load and usage around the home. The only reason I haven't given 5 stars is because I have not yet experienced running anything on the Tripp Lite battery alone (no power cuts, thankfully, although I have used the "Test" button twice, which checks the battery-only supply for 10 seconds). I promise to UPDATE the review if I think it will help your decision to buy one for your needs. Another techie friend of mine also recommended this brand or APC, so I don't have buyer's remorse. It's very simple to unpack and install and has a USB interface if you want to monitor its features from your desktop. For me, the display alone is enough reassurance. I recommend this for anyone who has a small office running critical hardware, or for a family entertainment center. Just be mindful of the technical loads/ratings you need. Watch also for TVs and PC Monitors, as these will suck the battery dry in minutes, no matter the brand or battery size. Overall, it is therefore a great backup for shutting things down gracefully and for coping with spikes and surges here in Florida (a frequent occurrence). Well worth the money I paid.
This is a superb piece of equipment at a good price. It is easy to implement. It is quite heavy and does take up significant space. Supplied wires could be longer to accommodate placement. On a rack or on the floor, distance to power and to equipment matters. I give it top ratings nonetheless. Then again, I am yet to suffer my first lengthy power failure.
