Summary: I've had my APC UPS back-up 650 for about 3 days. I don't know what you expect me to have evaluated within that time period. It seems to work as advertised. It is as I had expected. Ask me again after 1 year. By then I may have more thoughts of some value.
Summary: I was disappointed that this UPS had no software support for an iMac. The unit works great but I was use to the software telling me if I had a problem when I had a PC. Shipping was very slow also, that needs improvement.
Summary: I have used APC products for 20 years and find this one like the rest- well made. I have only had it in operation for a week so I can't attest to the long-term aspects. I use this to power and protect the satellite dish power supply and receiver-recorder and protect the TV. The TV is only protected and is not connected to the battery-backed portion.
Summary: Received the order right on time and in perfect condition. Unplugged the old unit (12 yrs old) and original battery. Moved all the equpiment to the new unit and have not touched a thing since. APC is the product of choice.
Summary: This unit was doing a great job until a power surge in a bad thunderstorm took it out. I had only had it for about six weeks. The good news is that it saved a laser printer and other computer equipment.
