Renaisser make fantastic Surface Pens at great prices and the Raphael 520C USB-C Charging Pen is a great addition to the range. I love that this grip is about 1/4" (6mm) longer than other Raphael models. It feels more comfortable in my hand. I use it extensively with Adobe Lightroom and Adobe Photoshop. The pressure sensitivity is accurate and great responsive. USB-C charging is quick and convenient with the included cable, and offers incredibly long battery life when fully charged. My only suggestion would be to pair this USB-C pen with the top programmable button on top of the 520BT I wouldn't be surprised if Renaisser has something similar in the works though!Overall this is a great surface pen for about 1/3 the price of the Microsoft version.
