Review on Surface Microsoft Pressure Sensitivity Platinum by Darian Massey

Works without installing additional software. I use it for Surface Pro 6 and haven't found any problems so far. Very, very, very small problems. It uses one AAAA battery (smaller than AAA). So you can't find it in your regular grocery store? The product says it usually lasts a year and a half. We will see. an additional pen tip is also available. but I'm wondering if I can keep it that small until I need a replacement (I'm currently keeping the original packaging so I don't lose it)
