    I had no issues with installing this. I wanted a UPS for the cable company's VoIP box, cable amplifier, NAS and network switch. The previous APC one that was over 15 years old could not be resurrected with a new battery -- last barely a few months. I have not had any issues with it.

    Each time the toaster or the blow dryer blow out the power, the wifi goes too. No more waiting for the wifi to regain consciousness. This paid for itself on the first try! I only have an issue with just one side is the battery and the other side is just the plugs
