The stylus feels cool to the touch when you hold it and is lighter and slimmer than the Surface Pen. The tip of the stylus is slightly less rubbery than the stock Microsoft HB nib. It's an excellent feeling and it's very quiet on the screen. Battery life for me is months of use on a single 1 hr charge and the auto sleep function prolongs battery life as well. This is my primary stylus on my Surface Pro 7 and works great on the Surface Pro (X,6,5,4,) Surface Book, Surface Studio, Surface Go as well as a number of different tablets created by Dell, HP, Lenovo, etc... it is not recommended for devices like the Surface Pro 3 that don't support tilt data (MPP 2.0) and may not work as expected.
If you don't buy this stylus from me the correct place to get the stylus is on Amazon from stylusman. There is a handful of other stylus that look like this, with different settings and manufactured in different countries. They are not the same. Stylusman does some of my shipping for me and is a fantastic person with exceptional customer service. The difference buying from me is that here you get the Pen Tool for free so you can remap the side buttons on the R520 to do your evil bidding. Here I provide you support and there he does.
