Bought a few of these 850VA, 1000VA and 2000VA RCT UPS's for an office that switches over to a generator during loadshedding. Works great, and they don't make a sound, so quite seamless. If it weren't for the lights that go off you wouldn't even notice that loadshedding started. SA Plugs at the back makes it very easy to implement. Really great products!

Unit is fanless and thus is rather "silent". When operating on battery mode you can hear a buzz but nothing intrusive, it doesn't feel hot to the touch - I've felt hotter UPS's. It comes with a power plug and rather short USB cable +-1m. The software used to control the UPS seems to work well enough, it is on a CD - there is probably some website that you can download it from (called ViewPower).

It has a standard South African plug on the back which is nice.

Using it to keep a screen, laptop and router up while waiting for the generator to kick in ~30 seconds, does the job, cant complain.
