    Works well and looks good, but feels kind of cheap. Too light! I'm used to the old, heavy bulky equipment I guess.

    The size and features of this UPS were ideal for our needs. I recommend simulating a power loss so you are aware of the alert tone and make sure you don't obscure the on/off button with a plug.

    Waited 2 months to review and so far no problems whatsoever. Its a product , of course, that will be truly tested in a long term power outage but I'm hoping that it will be there when I need it.

    You’ll need a backup battery for those pesky outages. However you will need to read in detail. If you’re running a gaming setup and the power shuts out. You’ve got 20 mins to shut your stuff down. So no loss of information and time to save. If you spend more Money though you get longer with more power. Just read in detail before you buy.

    I got this for my son last year for college and just got it for my daughter for when she goes to college. It is nice knowing that if they lose power they can still charge their laptops or phones or have a lamp that lights up for them
