The active area is more or less the same size as a Wacom Intuos pro medium, it has a relief that provides a not unpleasant sensation in use, although it remains far from the experience of traditional techniques.
The pen is pleasant to grip, it is neither too heavy nor too light, I find it even nicer than the Wacom pen. However it runs on battery and must therefore reload via a wired connection that connects the side "gum" to a USB port on the computer. During the ten hours that lasts recharging must therefore work with the stylus attached to the computer. It's embarrassing, quite unpleasant but nothing dramatic either. And once you are responsible alone for 800h (announced).
8 hotkeys (express keys) are programmable practices. They do not seem exceptional quality, I am waiting to see how they fit in the long term. That said the key to express my old Intuos 5 is not super strong either: one of them already working anymore after about a year of use (daily and intensive). I have not yet configured 16 digital shortcuts that are on top of the active area, so I can not comment.
As I said at the beginning the drivers are wound to install, there is conflict with Windows loads, and it took me forever to reach the tablet operate stably with all my software. The control panel is full of bugs but just about usable. Still very limited ... The product's overall finish is medium, it is far from the appearance of a Wacom tablet.
However, and this is the most important, once it is installed, the battery is charged and the pen that really starts to draw, the Huion H610 Pro is excellent. It is very accurate and pressure sensitivity is simply phenomenal, better than my old Intuos 5, whether in Sketchbook Pro 2015, Photoshop, Gimp or Manga Studio 5 (Clip Studio Paint). So yes it has some unacceptable defects, software is rotten and average finish. But it offers such mastery of the line for a quarter of the price of an equivalent Pro Intuos handily it deserves its 5 stars.
