Rated 5 out of 5 by from Nice Product, and good valueTripp lite impresses once again with this one. I especially like the mute feature instead of having the alarm go off when the power goes out in the middle of the night, waking the whole house. I am hoping this out lasts my last APC ups which died after just 3 years.

Rated 5 out of 5 by from It worked for meI've had this product for about 5 months. I paid little attention to it till now. It shut off at the moment of a power surge. I believe it protected my electronic equipment. That's why I purchased it. It worked.

Rated 5 out of 5 by from They can shut down unexpectly!!!They are a nice unit, heavy by weight. They do generate more heat then other units I have used in the past. I had two just shutdown on me! Running nothing more then a cable modem (unit1) and a TiVo (unit2). I was on generator power so my power quality was good but not perfect, however a UPS should never shut down without warning. They could use better packaging, I bought 20 units, the foam packing was damaged on most of them. However only one unit had a small chip in it. I now have them all in service, still worried why two would just quit on me...
