The Armor Z2 is Zyxel’s most high-end product to date in its networking portfolio, which includes a range of NAS units, extenders and power line adaptors as well as a number of products aimed at business users. Although the company is not quite as big or well known as some networking brands, previous Zyxel kit we’ve looked as usually been quite nifty, often with a feature or two that stands out, good performance and decent value for money as well.
