    Good value vs. the competition. It’s about the size and weight of a brick. Power hasn’t gone out so I don’t know about the battery back up function.

    This unit is great for when you have a power outage. You can still operate a laptop, light, phone long enough until you get settled in.

    Great packaging. Easy to follow instructions and quick installation. The product is working as described. Although the system is basically plug and play, I would still recommend users not familiar with this type of equipment to read the directions throughly to understand the power usage of the devices that will be plugged in to the product.
