Good deviceArvosana 4/5
After several blackouts, I decided to buy a UPS. The device is really quiet, which is important for a home office or living room. Literally, you do not hear a thing. The lights can be a bit too intensive (I give it one start less only because of this), but I have placed so they are not directly seen. It has the standard electrical sockets, so just plug your devices directly and use.
