I have a HP Spectre Pro x360 G2 (product number T5Z53AV) for work that was purchased in late December of 2016. The HP stylus at the time would not work, so I have been using a Dell version. I am not happy with this Dell version, so I am wondering if any of the current pens by HP with work with this version of the HP Spectre. I have tried to find the HP Pro Tablet Active Pen that seems to be recommended, but it is either outrageous on cost or not available directly though HP. I have also recently tried the HP Active Pen with n-trig technology, but could not get it to work. Any thoughts or help are appreciated.
