OPTI-UPS Enhanced Series ES1500C Review
|
I've had my UPS OPTI-UPS|ES1500C 980W for five years. It has performed flawlessly with no problems whatsoever. I found that the UPS battery lasts about two years with continual use before requiring replacement. I purchased the UPS to protect my electrical equipment from power outages and power fluctuations. I can find nothing bad to say about these units.
These are the electrical devices that I have connected
to my UPS:
computer, computer monitor, telephone, computer speakers, plasma
tv, telephone answering machine, printer, tv cable box,
playstation3, stereo receiver, stereo speakers.
