Summary: At the time I bought my first unit in July 2004, it was my understanding that this unit offered better power regulation than the cheaper units. It also came with a replaceable battery, the power to handle a 19 inch CRT monitor, surge protection for both telephone and ethernet cables, and a layout of good design. At $100 to my door this is a great value; so I did not hesitate to buy a second one in March 2007 for my other computer.

Summary: Living in Florida power issues are a constant worry, not just in hurricane season. This power backup is a great worry reliever. It gives a loud beep whenever the power is interrupted. I have the computer in another room and the beep is loud enough to wake me up if the power goes out in the middle of the night. When this happens my alarm clock looses its settings and now I never have to be late to work again because I will know to re-set my alarm. Highly recommended battery solution.

Summary: I've used APC Backup units in the past, and I am especially impressed with this one. Connecting the battery and getting it back into the unit turned out to be a little bit of a puzzle--I hate trying to figure out those engineering drawings that they provided. I plugged everything in and charged up the unit, then ran the self-diagnostic test and it shut down my computer! I ran the test a few minutes later, and everything worked fine.

I'm impressed with the run time--about 20 minutes on my system with an LCD monitor and a tower PC. The software provided (Powerchute Personal Edition) seems competent and even provides actual load information, something my ES725 did not do.

The unit supposedly provides power regulation as well as battery backup, but I have no way of testing that.

The only negatives I have for this unit are that I had a hard time finding an out of the way location for it, the power plug is not flat and therefore sticks out from the wall, and there are no data or coax protection circuits on the unit (there is telephone line protection).

I purchased this unit at CompUSA with free shipping and a $25 rebate for a final price of
