Rated 5 out of 5★ by GL012 Great product if you have Dell Studio XPS Desktop It took me a white to find out that Dell Studio XPS 9100 Desktop need pure sine power wave backup battery if you don't want your PC to restart every time there is thunder storm or (in my case) when I sent printing command to my printer (that takes a lot of power and causes 1/1000 power outage no device feels except for my Dell PC).This Batter Backup is the perfect solution. I have no more issues with these reboots and my problem is resolved forever. The only thing is that it is VERY expensive. My pc cost about $1,700 and I had to spend over $300 in addition for this backup battery, but I have to say it does he work and is the perfect solution if you have Dell Studio XPS. 07/14/2011

Rated 2 out of 5★ by Seniormediator Functions Fine, EXTREMELY POOR Design This unit is a replacement of my trusty old APC. Like the other reviewers, I needed a "Smart" backup to protect my new 'Puter. This technology is still pretty expensive so first thing was to get over the sticker shock!. I used the "Ship-to-Store" option (NEVER AGAIN) and eventually picked it up at the designated store. I have a small area of floor between the end of my desk and a wall and this is where it needs to live.The design is terrible. First, the outlets on the back of the unit are very poorly situated. There are 7 electrical outlets (3 Surge only, 4 surge and battery) situated so close to each other that it is impossible to plug in anything other than a traditional 3 prong corded plug unless you don't mind blocking another outlet!! In today's world we plug chargers, Power Transformers, and any number of oddly shaped items into our power centers!! There are various other things on the back such as USB, RJ 7 or RJ11 phone jacks, an antiquated Serial Port, a reset button, the Backup's own Power Cord, etc. My solution to these design flaws was to plug Power strips into the outlets on the back, and bring them around to the front. I used a Sharpie to note on the strip whether it was Surge Only or Surge and Battery. Electrical Tape covers the extra outlets on the strips so I'm blocked from the temptation to plug multiple devices into each strip. It is an ugly nest of wires that is totally unnecessary. The sides, bottom, and top of the unit are all flat and unused. The outlets could easily be separated and moved to the sides and top. CyberPower! Design for the 21st Century!! 05/01/2013
