Power Inspired 1000VA Sinewave Battery Backup (UPS System)

I have several server systems at home which I needed to protect with a UPS. I wanted a sinewave unit and this one fitted the bill. It is generally well constructed although I feel the sockets on the back are a little flimsy.Clear display provides useful information. Device has behaved as expected in testing i.e. continued to provide power when switching off supply.I think others have commented on a smell. I can confirm this although it is not offensive and I suspect it will fade over time.I intend to buy a second one...
