Very quick delivery (two days by UPS). Immediate installation. Connections to a NAS and considered directly (RJ-USB): The software provided is not even necessary in this case (it does not add much more as info on a PC). I have since suffered power blackouts. The UPS has its office right away. It protects NAS Box, inverter and even phone and PC / screen (Almost) complete satisfaction. I plan to buy another one for other equipment of the house. A regret on automatic triggers: Supervision is via USB, so a single device. It is strange that there is not also a network RJ. The recovery of information between PC and NAS is not practical (NAS does not recognize the information on the PC, the PC can recognize the information of the NAS, but recovering a free app not well integrated with Windows (winnut ). Result: 1 single device may turn off automatically. ATTENTION: Equipment struck since. Battery totally and equipment HS, yet without apparent defects - sensible protection equipment were also grilled. Now I'm trying to get a replacement. I have still bought another one, because the function of stability and anti-power cuts are fine and no problem.
