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, Asus (NOT 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 your computer will work with a Surface Pen then the R520 will be perfectly compatible.
If you would prefer to order the stylus from Amazon, please only buy from Stylusman. There is a number of similar stylus being sold and I've tested many. They come from multiple manufacturing plants in multiple countries and go from horribly unusable to exceptionally good. The ones from Stylusman are the good ones and manufactured in Taiwan and not China. They have a white (not green) power light (new version is always on), improved pressure curve and a number of important improvements made in the last 9 months. This is where I purchase my inventory. Stylusman is great, great customer service and the same stylus. If you order from him I will get a small commission which I appreciate. If you purchase from me, it benefits me and my little girls much more and the order is fulfilled daily by Jgotech and shipped from the USA. If you purchase from Stylusman, he will provide you with customer service. If you purchase from me you will get the Tablet Pro Pen Tool for free and I will provide you with customer service. If you are looking at purchasing a stylus you will want our Pen Tool and Tablet Pro desktop software. Which is a great way to get something you need and support my work in making mobile tablet life better and better for all of us. Thank you for shopping here!
