    This battery is great insurance in case of power outages or power surges. We have a laptop with a non-charging battery so we can only use it with an electrical input. We need this battery to supply that laptop with a charge in case of a power outage so we can power it down properly. I am not giving it 5 stars because the replacement battery is very expensive so you're better off buying a whole new device after about 1 year when the original battery no longer charges.

    So far so good. The device functions like it should. I have 5 external HDs, a router, and a PC hooked up to it and it's usually at half-capacity. I wouldn't add too much more however as too avoid over drawing from the UPS. I have had 3 power outages since purchasing and each time the UPS did it's job. Would have been 5 star if they'd included better software. The software does not provide the ability to do e-mail alerting, which is a bummer. Overall, a good "set it and forget it" UPS. 4.5/5
