    It’s of great use to me. The electricity in my apartment can’t be fully trusted and this keeps my important appliances safe in the meantime.

    This has been a great purchase. I use it in my RV to keep my satellite system from detecting a loss of power when switching power sources and resetting and taking 15-20 minutes to reboot and acquire channels. Plus if there is a loss in power, it will keep the system on and connected for when power comes back in. Highly recommended.

    Best way to stop surge damage

    I have these for my television, cable box, DVR player for when electricity goes out and then comes back on with my generator. It stops the electric surge which I hear can damage the electronics. And it ops things running during that minute the generator gets going. With my parent now in need of certain equipment for care, I have one just for that. Keeps my mind at ease
