CyberPower BRICs Series 650VA LCD UPS

Hey I just purchased a Cyberpower BRIC 850V LCD UPS from Officeworks for $137. Seems to work fine with my ReadyNAS duo, including monitoring via USB cable. It's statused correctly at the ReadyNAS - remaining time and battery charge (from Status/Health) is consistent with the LCD display on the UPS (ReadyNAS reports as "CPS UPS VALUE, Battery charge: 100%, 43 minutes"). Have only had it for 2 days but seems great. Also did the power off test, NAS also correctly reported it was on battery power when it was, and correctly reported it was back on mains when it was. For the price, this seems like a good deal and easy to get in Australia too from Officeworks (I'm in Perth).
