    I currently have a 650 VA version of this UPS that backs up my router, PC and Screen. I needed a second UPS because of relocating my PC to another room. Since I only needed to back-up the PC and Screen, I could use the smaller model and save a few dollars. Being smaller in physical size it was easy to place.

    I love these things. I have one for each of my computers as well as one on my on-demand hot water heater. These things are great during a power outage and have really saved me quite a bit of hassle with short power outages. The only downfall, for me at least, is that they only last 3-4 years at most.

    Bought this for an elderly parent who uses an electric lift chair. If the building loses power, the lift chair will still function allowing our loved one to lower the chair and not get stuck in a laid back position. We have not had opportunity to use this device.

    a good size for a small-medium powered computer

    Does not have USB monitoring which is fine, it can keep a small-medium sized computer running for a couple minutes on full battery charge. Not sure if it can be silenced when power goes out. That is a minor thing, although I am sure someone will know the power is out when things do not turn on, the beep is just a reminder!
