Zodiac’s Active Wireless Stylus is an all-aluminum pen that works with the Spectre Folio 13 and Microsoft’s latest Surface products, as well as other OEM portable devices. Sporting 1,024 levels of pressure sensitivity, it allows you to write, draw and erase without issue. The pen itself takes a battery, and one is included to get you started. Much like other pens on the market, there are two buttons on the side, one for erasing and the other for a right-click. And if you don’t like it, there’s a 45-day money back guarantee. Can’t go wrong there.
